Hey Folks,
While I realize schematics are not yet available for the Astoria, I'm wondering if anyone could confirm the cathode bias configuration? Is each KT66 biased with it's own resistor, or are they biased with a common resistor/capacitor? The reasons I ask are #1> Every data sheet I find for the KT66 has some wording that states: "It is essential to use two separate cathode bias resistors.", or as mentioned, worded somewhat differently. #2> I'm considering building a JTM45, but cathode biasing the KT66 and maybe providing/incorporating the provision to alternatively use 6V6 tubes. #3>The Astoria seems to be one of the few amps to natively utilize the KT66 in cathode bias configuration.
Any Help Appreciated,
Gene
