Harmony H322 Bass Amp.......The "mini" Bassman from Hell !!

This video chronicles the nightmarish repair of a thoroughly botched early 1960's Harmony Model H322 Bass Amp, probably built by Lectrolab. Since it features powerful (7591) fixed-bias output tubes and four (8-inch) speakers, it resembles a "mini" Fender Bassman, but was plagued by yards of tangled added cables, ill-conceived modifications, muddy sound, low volume, and a roaring 60Hz hum. Fixing it was one of the greatest challenges I have faced, and actually required a few months "vacation" from the task to avoid either insanity or retaliation with an axe (not the guitar type) :)
Extra features include the opening of a very special gift from a generous viewer, visits from Jack and K.C., and a really special modification to one of the hot rods. Here is the link to the video discussing the special gift: • A Studebaker Tube Radi...

Please, subscribe to Uncle Doug and his merry cast of guitar wielding kitties!!! This channel should be one of the vital sites for AMPAHOLICS! Again Uncle Doug has brought to light another rare, probably unknown amp. I started my infatuation with guitars and especially amps in the early 60s when I first heard my long lost cousins from Wyo. play early Venture's instrumentals through a big, 2 speaker tube amp that was loud enough to make my body vibrate. I went home and got started trying to play "Johnny B. Goode" on Harmony Stella guitar with string action so high you could have shot arrows with it. My break through was when I could make the 1-4-5 chord change, and hear and understand them! I broke all but the low E and A strings but I got it right. I am 70 years young and when I play guitar I feel just like I did at 13! If that is not enough to get you to subscribe to this channel, then maybe you are not an AMPAHOLIC! Thank you Uncle Doug for sharing, and teaching us all, your vast knowledge and experience. Guitars and Cars, from the sound to the paint they are loud, powerful and exciting! Thanxz

Hey uncle doug i love these videos man keep up the good work! The perfect mix of technical insight mixed with a splash of humor now and then. I just finished a course about circuits and electronics so no i actually know what you are talking about and that makes watching these videos so much fun!

[@UncleDoug]

Thanks so much, Marijn. Best of luck with your continuing education.

Nice amp, and one of the most useful videos of yours I've had the pleasure to have watched, Doug. Thanks!

[@UncleDoug]

Thanks twice, PS :)

Thanks, Bennett. You too.

[@allencrider]

Thanks Uncle Doug! Every time, now, that I watch your new vid, I'm compelled to treat myself afterwards with the pure and true Fender/Texas sound of "Khruangbin Full Performance on KEXP".

[@UncleDoug]

Wow.....Rev......that's one performance I must have missed. I'll check into it.

[@curtislucka9954]

Great video for me - always appreciate a good hum troubleshooting saga. Added some good nuggets to my list of things to look for. Well done!

[@UncleDoug]

Thanks, Curtis :)

[@casinodeathfish8703]

Uncle Doug: You are as informative as you are hilarious. Great stuff. Keep it coming!

[@UncleDoug]

Thanks, will do!

[@DR-mp4gv]

I like your rundown Doug, you always teach new concepts.👍🏻

[@UncleDoug]

Thanks, DR. That's our goal :)

[@adenihil]

Such precise work ; so much attention to details ; applied patience and craftmanship to end up with this sweet sounding and beautifull device... And the amp is also pretty good too. 😄 Thanks U.D.

[@UncleDoug]

Thanks twice, Adrien :)

[@raycochrane3971]

Another one saved from abuse or dumping - well done, yet again.

[@UncleDoug]

Thanks, Ray :)

[@DonnTarris]

An incredibly fun way to learn about working on tube amps!!! Magnificent in fact ;-)). Always good smiles waiting within your content!

[@UncleDoug]

Thanks so much, Donn :)

[@timkoontz7370]

Very nice sound! Very usable! As good as or better sound than many fancier “vintage” amps.

[@UncleDoug]

Agreed.....and very affordable :)

[@Andy_Yates]

I laughed out loud at the brothel headboard commentary :). Another great one Uncle Doug and great food for thought around the grounding scheme. Hope you're doing well through all this!

[@UncleDoug]

That's our goal, Andy......glad you enjoyed it. We're embarrassingly healthy, and hope the same for you all.

Switch from Cadmium Flakes to Selenium....good move-what's next. Uncle Doug you inspired to build a 5E3 circuit while I am Social Distancing from the wife in my garage! Unfortunately the only odd stuff I found out there was some rat poison and I refrained from sniffing today. Great work you are a special human being!

[@UncleDoug]

Thanks, Michael. Good luck with the 5E3 project :)

[@WillyMcCoy50]

Subbed and hit the "notify" years ago and this gem of a video is only now appearing in my feed! Always a hoot to watch you re-engineer the cool old amps I grew up with! The new throttle response must be a lot of fun! The '34 is looking good Doug!

[@UncleDoug]

Thanks, KM. It's always good to hear from you. Yes, it's a real handful once the revs get up around 2500 or so.

[@bruceferrero8178]

Very nice! The design engineer would be glad to see and hear it back in shape!

[@UncleDoug]

As will the owner. Thanks, Bruce :)

[@bobross6802]

I love the smell of burnt selenium rectifiers in the morning ... thanks, Doug !

[@UncleDoug]

It's deadly on Coronavirus, Bob, and everything else......unfortunately ;)

[@oldguy5381]

Tunnel Ram, whooowee now that’s a parts chaser. You did a fine job of it. Have fun

[@UncleDoug]

Thanks, OG. It made a huge difference in performance with no drawbacks.

[@glennharpell5584]

Uncle Doug. I've watched you for a minimum of 3 years yet never posted. The wealth of knowledge I've obtained is immeasurable. Thank you from the bottom of my heart. I now have built several amps as well as repaired tube and solid state amps. Thank you for all you do.

[@UncleDoug]

Thanks for your very nice comments, Glenn. It's great to hear from you and to know that our videos were helpful. Keep up the good work.....we will too :)
