I did find an example of this 6AU6 type of tremolo on a fixed bias 6BQ5 PP amp The Lectrolab R600C, the 6AU6 Tremolo does NOT have a bypass cap on the 150K Plate Resistor The bias "mixer" is very interesting, a resistor bridge, Any comments on that arrangement? https://lectrolab.wordpress.com/lectro...

A cap paralleling a plate load is rolling off high frequencies. I have to believe it should be 680p, targeting >3.4 kHz, rather than 6800p which would be 340 Hz. Agreed, Was just wondering why I couldn't find anybody else on the internet commenting on the SilvertoneWorld,com schematic specifying .0...

Looking through all of the schematics on the el34world.com "Silvertone.pdf" (Link below) I see that the Capacitor parallel to the 68K...
