Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Re: Durn it... -> CCS?

The rule of thumb I've been using on the output stage is... Set the voltage on the pentode CCS equal to the plate-cathode voltage of the output tube. This gives you the compliance you need plus some margin.

On my 45 amp I have 180V across the cathode resistor to setup DC coupling, 275 Plate to Cathode on the 45, 275 across the 6bq5 pentode CCS.

Have fun!
