Title: Cathode Follower Operating Conditions
Post by: Loon on May 30, 2014, 02:33:38 PM

Can someone please tell me the operating conditions of the cathode follower in the stock Crack with Speedball?

Eg, Cathode current, anode voltage, anode current

Want to work out the effect of changing grid voltage to -50V.

Cheers

The Speedball fixes the current to 30ma through each half of the 6080.

The plate voltage is plate to cathode voltage, with cathode voltage set by grid bias.
