Welcome to MyTubeAudio. A truly different kind of repair shop.

MyTubeAudio, LLC., is a West Michigan-based company that offers “While You Wait” service for tube amplifiers of most any make and most any vintage.  I’m licensed, insured and experienced – I have been involved with tube amplifiers for over 25 years.  Considering MTA’s deep inventory of parts, and the experience of hundreds and hundreds of documented amp repairs you shouldn’t be surprised to discover that most tube amps can be repaired in just an hour or two.  Why not cut out the middle-man and the three week wait and head right to the bench?  You can see your amp get worked on, you get your questions answered, and you’ll KNOW what’s been done. You can get to know your amp tech, and let him know what’s important to you. All work is performed “live” by appointment only – you are always next in line at My Tube Audio, LLC.  Do you have an important show coming up but can’t risk dropping your best amp off somewhere not knowing when it will be done?  MTA LLC can help you.

What? You’d rather have something retro and custom?  You’re covered.

My Tube Audio is also an official dealer for Mojo products, who make an impressive  line of vintage-inspired classic tube amp kits.  I can build to order / custom modify anything you find on their website, so if you’re looking to buy a classic amp but would rather have something in like-new condition without the boutique-amp price, check out and let me know what you’d like to do. It’s a good way to get a great amp for less cost than finding/buying/shipping/repairing a vintage unit.

I also offer electric guitar service – just about anything you might need outside of frets and paint. Wiring, mods, pickup changes, setups, intonation and hardware updates. You can even bring in your own purchased “goodies” and let me do the tricky part. What? you bought new tuners but they are a larger diameter?  No problem. MTA LLC has a well-equipped woodshop that can help.

Amateur Radio fans, please take note. I have a great deal of radio restoration experience (domestic AND European) and can help you get that vintage transmitter, receiver or transceiver back up and running. I have a whole bench full of gear to support radio repair, including test equipment for measuring alignment and sensitivity.

Hi-Fi friends, MTA LLC has you covered, too.  Beyond the basic performance checks, I can measure THD and Intermodulation distortion values, and a host of other aspects to make sure your tube HiFi gear is really operating like it should.

As for the site – Well, I don’t get enough free time to be doing a proper job of it, but I  add things when I can.  Up here on the front page I am going to continue to add more repair and project photos, with small comments here and there. It’s not as good as full pages dedicated to each item, but it’s better than nothing.  Enjoy what you see and feel free to contact me via the Email address shown in the photo above.

2016 – The New Year!

Posted: January 20, 2016 in Uncategorized

Thanks for visiting MyTubeAudio. 2016 is off to a great start already!

The Business –

It’s been a busy couple of years – the daughters are growing like weeds, my career changed paths again, and the amps keep coming. About the only part of my life that feels consistent is the repairs. For a few years now I’ve been doing exclusively while-you-wait repairs for tube gear, one, two or sometimes three per week, and I’m get nothing but wonderful feedback from the customers.  As to stats, well, most repairs take around two hours, sometimes more or less, but the average bill seems to hover below $100 when I’m billing $40/hour plus parts.  I had some feedback that the site was looking a bit dated, so I figured I’d better take a rare quiet evening free and update things a bit.

The Bands  –

The Voice and Rocket 8 are both active these days – The Voice had a strong show at a local theater and just about filled it – we made well  more than enough to cover costs plus pay the professionals who took care of lighting, sound and serving the crowd.  During that show we showcased some new material that we’ve been working on the in the last year and released some new material on iTunes as well as our back catalog for download. We followed that up with a nice Christmas show and are starting the new year by doubling-down on the remaining unfinished mixes, which so far are sounding pretty tasty.

Rocket 8 has been keeping a steady clip, so to say, at about one show per month per the PLAN, and in the last year we added a second guitarist, which really filled things out and has allowed me to get more familiar with keyboards, adding more texture and breath to many of the danceable 80’s covers we specialize in. There is a demo on YouTube out there now – I’ve been mixing the live audio multi*tracks for the past  few months  as time has allowed while Glen has been putting together scraps of video to make a medley of material highlighting the band’s offerings. Hopefully it will bring us some new venues to ply our trade in.  There are rumors about a possible Mac Island show this year – we’ve committed to it but have to get the venue on board with it- there is a good chance it will happen for 2016. I think the last time we played there was summer of 2013. We’ve also invested in gear again – adding a digital board (Midas/Behringer X32) and picked up 2 x 18 JBL subs and 2600W of Crown power to drive them. Active monitors were also added, and the upshot of all of the investment was deleting the racks of gear we used to carry – a cleaner, simpler PA with tons of headroom and all of the FX we would ever need. We don’t clip anything anymore and are getting very good feedback on the sound overall. iPad access to system tuning is a wonderful thing – you can walk around a room and do anything you might want to, and save your changes too.

The Site –

I do have more repair pictures to upload -I’ll make an effort to get them out there this year, I promise!!  I get a lot of comments from customers that they have indeed taken a look at the site before calling, so it’s time worth spending.  I’m a bit hesitant to publish my contact details here, but let’s say that I can be reached most easily via CraigsList Grand Rapids where I have kept an active ad for years – Search Tube Amp Repair under For Sale – Musical Instruments for all the contact information.

The Studio –

On of the benefits of the Rocket 8 transition to a digital board is that all the rack gear came back home where it belongs. Not that I use it much but it’s nice to have everything back in place and wired up for service and not out in harm’s way.  As part of the new job I started in November of 2015, I took some severance pay and invested in a capable laptop, and that has resulted in a lot of recording and mixing “completely in the box” as they say. It’s addictive in some ways, but I too, like so many others have noted how it lacks warmth. I’m using Adobe Audition on that machine, as I used it with my former job doing voice-recognition prompts for so many years that it was a natural choice. I do miss my extensive plug-in library that we had on the corporate license, but that can be cured a little more investment. I’m finally happy with a PC that can handle multi-track audio gracefully without complaint. Funny to think I had to lose my job to get to that point.

The Day Job –

It took a couple of months, but after Visteon shuttered the doors in West Michigan, I landed on my feet (with more than a few former colleagues) at a good company, Gentex, just a short drive away. I couldn’t be more pleased, as it’s a well-run place. My current role is as a Senior EMC Test Engineer, so once again I’m playing with some really expensive toys, interesting antennas, and radio. My latest work will have me playing around well into the double-digit GHz domains, looking for truth and harmonic content above the noise. I love this kind of work, and the research that goes with it, I’m back into a learning mode and that feels great. Good to be employed, too!

I wish everyone a safe and happy 2016 – if you are considering having some tube amp work done, please get in touch – we can fix your amp together,quickly and have fun doing it, for less cash than you’ll likely pay elsewhere.  The best part is you take it home with you the SAME night. That’s what while-you-wait service means – NO WAITING, and exactly the things you want done get done, and done right.

Here is a random collection of photos from 2014 work.  I’ve been terribly busy, 2 bands, engineering day job, family (2 young girls + wife!) and tube work… lots of it.I don’t have much time to post here but I think I can upload a bunch of new pix and call it good for now!  (oops – I now see that they upload in a random order… if I get time I will try to sort them later. )

By the way, the “While-You-Wait” repair thing is going GREAT!  It’s so much more enjoyable and the customers are loving it. I should have done this years ago. I no longer take drop-off repairs of any kind, but I’m doing morework.  2015 started with a bang – usually 3 appointments per week. Let the solder fly!!

Epiphone Electra needs a heart transplant

Posted: January 25, 2014 in Uncategorized

This Epiphone had an issue with a bad photocell/lamp combination – a special optocoupler that is no longer available – and so no tremolo.  I managed to retrofit a new lamp into the original assembly and only had to make sure the current driving it was within spec and still performed well in the tremolo circuit.

SRV Strat Teardown

Posted: January 25, 2014 in Uncategorized

Sometimes a guitar just needs to be blown apart, gone thru end-to-end, everything cleaned and lubed and tightened, and anything replaced that’s not up to snuff. Then you do a complete setup from scratch knowing that there are no hidden demons. Such was the case with this SRV strat.. Also of note here is the new second bench area set up for RF and other non-tube work.







Well, I have not posted here in a very very long time. A few changes have happened.  We have daughters, 3 and 5, which take a lot of our time. That’s one reason, another is just the speed of life. So much to do, so much remains undone each day. I have acquired the address, which is kinda cool. The biggest change has to be a shift in our general business model, namely, I now work solely on a “while you wait” basis.

No more drop-off, pick-up of tube gear requiring repair. We make an appointment, we fix it, and it leaves the same night. The feedback has been very good on this. It was a good choice, and is possible because I stock a lot of replacement parts, well-organized. I have been as busy or busier since this workflow shift about a year ago.

I have been collecting some pics of the work – not as consistently as I should, but still, there are a lot of photos to post, and I think I need to get a few more up here today.  As I type this, a blizzard churns outside of our Holland, Michigan home.  The kids are home, school was closed due to weather, and there is a certain Zen to being in a warm place as the wind rages.

Ampeg B15S – the Portaflex.

This amp has a history, most of which I know nothing about. But this is one of those stories that makes legends, eventually. It goes like this… it used to live at a Theater (as in stage play theater..) for probably the major portion of it’s life, and one day it almost hit the dumpster during a cleaning-up operation as the management underwent some changes. Luckily for me a good friend spotted it as it was literally being carried out and detoured the folks carrying it towards his van. It was gifted to me and aside from being a little scratched up, it’s in fine shape after minimal servicing. It even has an original set of USA 7027’s in it, which measure fine. They make 70-80 watts RMS clean. As the Altec 15″ (original, it appears) speaker seems pretty efficient, this unit can easily keep up with a drummer and as such it’s the main bass amp in my project studio now. My friend Steve uses it whenever the old band gets together, and we love it’s tone. It sits on an 80’s Ampeg 4×10 cabinet, and the combination of the two can move a lot of air. It also makes a nice looking bass stack. The 4×10 was an eBay local purchase – local,.. OK, Bay City, but that’s still local enough..) where I paid 75 dollars for the cabinet with 1 damaged and theoretically 3 OK speakers. In the end I had two of the drivers reconed, ($70) and had to repair the grille. Overall cost for this stack was about 150 dollars. How’s that for a deal? Like I said… the stuff of Legends… :o)
