Good morning folks. I have run into a bit of a problem with an amp I am building. It is intended to be a bass amp, so ideally distortion should be as low as possible. I sadly don't have a schematic drawn up yet, but I will try to have one up this evening. Here are the basics though.
I am using Weber Transformers. Both designed for 80 watts. I am also using the output section of the 6A80 weber amp.

Right off the bat the distortion was rather farty, so I changed out the .1 PI coupling caps to .02 with great results. Sadly it distorts very early.
my topology is as follows
1/2 12ax7 >>> volume >>> 1/2 12ax7 >>> baxendall tone stack >>> 6AV6 >>> 12at7 PI >>> 6l6 quad
I will also measure the voltages and post them as soon as I can.
Sorry for the vague description. I'm just running out the door but I will try to have everything useful up by this evening.
Thanks.
Cory.
