I see 1k5 screen resistors. You mean grid resistors @ 5k6?

cheers,

sort after?
you mean sought after?

happy Festivus!

or replace steel nut with a nylon nut....

Not really expensive(about 300eur per piece),in EU Mercury Magnetics cost 50% more.

in the US Mercury cost 50%+ more

Yeah, we have different definitions of expensive.

we do??

I think it would have 275uF filtering as they're series wired.

Perhaps it began life as an EB202-S 50 or 60 watt that had been modified. The 5th and 6th knobs were previously where inputs for the normal channel resided. Is V5 a 6AQ8 (ECC85)?

Sorry - that's all I've come up with.

What are people here using for bias pots? I've been using the CTS screwdriver-adjustable ones but they only come in 10K and I find that range a bit limiting. Does anyone have a favorite bias pot option they're using? I like to have things externally adjustable so panel-mount is key. The range is us...
