ADM | Re: brown trem (was Re: Fender brownface tonestack) Looking at the schematic, the brown tremelo circuit uses 2 1/2 tubes, 1 1/2 for an oscillator with two (out of phase) outputs and 1 tube for a frequency divider mixer circuit. I was wondering if anyone has given any thought replacing the oscillator section of that circuit with a few op amps, but maintaining the tube signal path. As an aside, any thoughts as to why the mixer tube in that circuit is biased so cold? (4k7 bias resistor on a 12ax7 tube) |
