Selmer service and speakers installed for a customer

– Some minor issues corrected, cleaned and Alnico Celestions put in from another Thunderbird. Electrlytics changed to correct values, Tremolo serviced to get it working! Anode resistors removed from Rectifier diodes (they never had them!) Some tubes replaced and Power amp module wiring neatened up (PI anode and cathode resistor values changed to increase headroom before distortion). All knobs changed to cream. Still needs push button tops. Lovely sounding vintage amp breaks up really musically!
