Tim - Thanks, but you missed the main point which is the fact that the trimpots are having no effect on bias. It's as if I didn't connect the IBAM board (which I did).
I want to try IBAM out using the original Fisher 7189s in case something goes wrong. If something goes wrong and I damage the original weak outputs, then there is no loss. Once I'm satisfied that everything is OK and that there is no danger of redplating/damaging the output tubes, then I will install the NOS-NIB 6П14П-EB tubes and readjust the IBAM trimpots to suit the new tubes.
Mondial - Thanks, will check...
