Convergent Audio CAT JL3 tube biasing/manual

Many thanks to Bugman03 for his offer and Dearing for the input. I now have a copy of the manual.

I have a good friend who had the JL-1 monos. Like many Audio Research amps, it's not possible to bias individual push-pull pairs - you can only bias an entire bank of tubes, which requires owners to purchase very carefully matched octets. I'm not criticizing the sound of the amp - the CAT amps are spectacularly good and have no equal in their ability to drive virtually any speaker, but they can be a real pain to tube and I suspect you're going to hear this from owners here.

I can scan and email the manual that I have as I have the same amps. My email is dabugman@mac.com. The manual is only a few pages.
