This adapter will not work on any amp the 6SN7 Filament has to be run on AC not DC and it will not work in Woo amps that have the two 6SN7s in series running off 12.6 volts. plus
the Woo sockets are recessed and this adapter will not fit.
First you would have to know if your amp runs the 6SN7 off AC or DC before considering one of these.
This is great to know... and great that I won't have this dilemma. The OTL is my sole tube amp for now. You made a beautiful looking adapter, by the way!
