6A3: That is a much better topology.
No more choke in the output stage bias.
Click to expand...

bias choke can be discussed either
it was usefull to develop my 211PP
to avoid full power grids trigger
(ended with 6BX7 CF direct coupled A2 drivers)

so still i have this choke waiting somewhere....!

but let my develop this dirty and cheap amp
it really sound nice
Hammond irons cheaper than others
but not plug and play 124F need tuning
and auto cathode bias need bigger opt
cheers claudiomas
