The Amp Garage

I have done a lot of tinkering with the 2204 circuit. As others have mentioned, it could very well be the tolerance of components. One of the first parts I would check is the .001uf (1000 puff) bright cap on the gain pot. If one amp had a cap significantly on the plus side of tolerance and the other...

That first stage is very susceptible to hum. Before I would try to reduce hum by change that resistor, which is a bandaid type fix, I would try other means. First, where are the heater wires? do you have them twisted and as far away from other signal wires as possible? Second, the wires going to the...

can you hook it up to a signal generator, scope and dummy load and see what is going on?

can you post a schematic so we can see what you are trying to do?

I've tried the lace pickups, all the colors, and while they are quiet, they just seem too "perfect." No character really of their own. The Gold does sound pretty good in the neck position for a funky rhythm sound, but other than that, they don't do it for me. I have been using the Hot Noiseless in m...

woohoo, post number 2 yes, that makes sense. The 150 ma would never be seen across that 1K resistor though (unless there were the magic smoke billowing from the amp). to answer Rockstah's question, yes, you can put the 1K 25 watt resistor in a plexi in place of the choke. What may happen, however, i...

Hi, this is my first post, go easy on me! "-The R is just an R and will sag 1000V per ampere. At 25W dissipation, this accounts for a max draw of around 150mA (or a max "sag" of 150 volt) across the part. We can also assume this behavior to be consistent across the guitar frequency range...
