Biasing Help Wanted

[mchurch]

I have just finished helping a friend rebuild and early version of an Audio Mirror set of mono blocks using the 6C33 Russian Tubes. The mono blocks have biasing pots for the 2 tubes in each amp and I have the voltage information for the tube but I am not sure where to read the voltage to adjust the bias. Is there a particular pin for reading the bias? Cathode ? We cannot find any instructions and I don't want to install new tubes and kill them prematurely.

Any help and advice would be greatly appreciated I know this is not a Bottlehead issue but I figured that some of the resident tube experts might point me in the right direction.


Regards

Mike

There is not enough information in your post to provide anything useful, unless someone here already has these amps.

If we had a circuit, we could tell pretty easily. If we had the "voltage information" that you say you have, it might help. If you have any other information, that might help too.
