Are 1967 Showman amps (6L6GC tubes) cathode biased or grid biased?
Patrick Selvedge at Mercury Magnetics told me that unmarked Blackface (Dual) Showman (4Ω) heads are actually more common that the 8Ω heads!
Hi Mar’ I have just the 022889 serial so it is suposed to be 4ohm isn’t? Regards
The Blackface Showman output transformers (4Ω or 8Ω) have two possible number codes (excluding the DATE CODE). The number listed on Greg’s date code page as the crossover for the 4Ω transformer is incorrect due to a transposition error (the penultimate number 9, should be an 8.) 4Ω 125A29A > 022889 (corrected) 8Ω 125A30A > 022897
I had mine modified for gain and my tech put gain pots on both channels and added a middle to the first channel.Among other mods.It screams!Reading this info it says fixed bias,but my tech says no it’s not,he might have added a bias adjustment during the mods?The serial # on my chassis is A 06124 and is the AB763 schematic.As they say in this info?Hopefully this might help you, Jeff.
