The Amp Garage

Pass. I’ve been around long enough to know. I’ll keep my money in my pocket. Concise enough?

Those RECPRO caps - nice idea, but I'd rather use Mallory 150's and pocket the $28 a cap saving. Plenty of good caps out there for a reasonable price. I'd look at Zoso before I'd go this route. Spending $300-400 on caps when that's only one ingredient in the tweed sound recipe seems quite foolish to...

I tried adding a top boost when I found a very accurate kit years ago. It just didn’t work well. Sooo much noise and very sensitive. I know if I stuck with it, I could make it work, but I wondered if it was worth the trouble. I still have the kit and could take another swipe at it, but I’ll have to ...

I agree. I have a 63 AC30 I restored about 20 years ago. Those parts are long gone. Even if you do find used parts, the heat and years make them fragile.

I have a Sterling Hiwatt that I recovered. In the course of the process one of the pieces of piping disappeared.I have looked and have not been able to find the right size. Does anyone know where I can find some.

Have any of you ever heard of the #41 mod or the #44 mod? That's because Tim Caswell doesn't talk about them. Tim returned to a quiet life and was sought out initially by George Lynch, but Frank Levi couldn't stop bragging about his "accomplishments"(a New Yorker with a big mouth. Who knew?). Tim st...

Yeah, a schematic would be reeeeally nice. I havent been able to find schematics on the ultraphonix amps. Only video demonstrations on youtube.

The overdrive is not more than I can handle as a player, it is a problem and not musical. I will try to post some audio, but the signal goes from clean to very buzzy. The treble makes it worse. Rolling back the volume can get it clean, but very quiet and there is no transition like it is supposed to...

I built an express several years ago and had an issue. I shelved it and recently pulled it out again to try to figure it out. I went through it and voltages are good, wiring is correct, controls all work like they are supposed to work. I jumpered the input into the phase inverter to bypass the first...

I have a 1960 Harvard that I got in the original cab that was cut off into a head. I had a cab built and put a Weber 10A125. Couldn't be happier, but I wanted an original sound. This is my favorite tweed amp. It gets the tweed tone, but doesn't over compress like a Deluxe or Tremolux. I put a Klon i...

Gary's voltage chart is listed under the TW files -> compiled voltage readings. I stuck it on a scope and it looks like it is only overdriving half the waveform. Im going to go through the wiring to make sure everything is correct and check all my solder joints. I did find out that the output transf...

Sorry, both are typos. V2 pin3 was 2.8vdc and V5 pin4 was 368vdc. Sorry, thought I fixed them when I previewed the post.

Thanks to all of you that responded. I can see the layout seems to be pretty important from what you guys are saying. I did notice the prescence seems to be acting like an antenna - especially as I turn it up. I did verify my voltages at the filter caps and the most any one of them was off was 3 vol...

So, I completed my build and I was really happy with the way it turned out...until I turned it on. I expected it to need some tweaking, but I figured it would come in closer than it did. There is WAAAAAAAY too much gain. I mean to the point of sounding like 2 Big Muffs chained together and maxed! It...
