The Amp Garage

I was hot on Gibson when I first shopped for a guitar mainly because every guitarist I liked played a les Paul. The first time I played a strat, I knew that single coils where right for me. I went on to buy a Korean made epiphone les Paul standard but lusted after the fender sound until I got a stra...

What kind of recording setup do folks use for recording demos and youtube videos? I have tried recording demos with a Tascam US 122 and a SM57 as well as several condenser and can never get even close to the sound quality I am looking for especially with any sort of overdrive.

Someone wanted me to look at a CHA 33 to see what was needed to convert it to a tweed style amp. The amp looks like someone buried it in the ground since the 50's but it fired up when plugged in (even has a set of RCA black plates that are showing very good on the tester). Volume was going in and ou...

I'm putting the final touches on an 18 watt that started as an 18 watt lite, I then modded it to a superlite. Not satified with that, I have since tweaked it to a Mazerati GT preamp w/ TMB and small changes into the superlite power section. It has a cathode bypass switchable boost, bright switch, an...

MC is sending me a new PT. They have great customer service from what I've experienced. Triode took 3 days to respond to my email and phone call.

[quote="M Fowler"][quote]It was working fine before I changed the circuit from a Lite IIB to a superlite.

I've been emailing a tech rep all day performing tests and he says it sounds like the HV winding is open. How does this happen? It was working fine before I changed the circuit from a Lite IIB to a superlite. I didn't even desolder any leads except for the primaries... We will see what he says tomor...

[quote="Phil_S"]Lift the center tap from ground and measure resistance from each end to the center tap. The ohms should be close but not equal. You can get the ends at the tube sockets without desoldering. Just pull the power tubes.[/quote] I have 86ohms on one lead and 1.8Mohms on the other. Not go...

[quote="passfan"]Is the high voltage winding center tapped and if so is it grounded ?[/quote]

Yes its center tapped and it is grounded with the heater center tap.

I have a MC 18 watt PT and OT I used in a Lite IIb build, I converted the amp to a superlite and now it seems like I have PT issues when i tried to start it up. All my heater voltages are ok and my wall AC is 125. The problem is the high voltage leads are putting out 350V on one and 0 volts on the o...

DAMN!

have you tried pulling tubes? I would agree that it could be the transformer but I've heard a buzz like that from tubes.

I can't speak for the 6.6k but I have built 2 pools with 5.2K Heyboers from RJ and they are bad to the bone! With humbuckers I break up at around 9 o'clock on the amp volume but can still get some authoritative clean before that point.

Does anyone have or know were I can find clips of a 2 EL84 rocket?

I have an 18 watt tranny set from an old lite build and would like to put them back into service.

thanks

[quote="solderstain"]I just took a good read through this for the first time, and am a little confused by what the OP is dealing with. Maybe he can clear up my confusion? :lol: Initially the question is about hiss... and later you talk about interference your guitar picks up and the phenomenon reduc...
