Not really a that odd tube and propably not the most musical, though it is sometimes regarded as a twin 6L6 in one
tube, as 832 is looked upon as a twin 6V6.
I have had ideas od building a two-tube SE-amp using 832, but 829 could be more cool. Got output transformers from China lying around just waiting to be used. A driver like 6SL7 or 6SN7 ... or a 6SC7 ...??!!
Below are some schematics for 829 single end designs that uses two tubes/channel.
Got the tubes, waiting for time to come ...
