I'm buzzing around, checking out EL84 amplifier schematics (a current fixation of mine) and would like to ask a question about the version of the ST-35 that is featured on this forum.
I'm very curious to know why there is a 100uF cap between the EL84 plate supply and the driver/phase inverter supply that is not connected to a stage in the audio circuit. Does this improve filtering to the driver/P.I. section? Also, would it take a very long time for the section in question to discharge once the amp is off without a load or bleeder attached?
Thank you for humoring me.
Glad to see that attention is still paid to the ST-35.
Be well,
Adam
