CHAMP ELECTRONICS -" THE VALVE AMP HOSPITAL"
NOTTINGHAM, ENGLAND
SERVICE OF A RIVERA KNUCKLEHEAD 100 WATT AMPLIFIER HEAD
"This is a Rivera Knucklehead 100wt head (4 x EL34's),
made in the big USA by Paul Rivera Research and Development Company,
Sun Valley. I believe Paul Rivera used to work for Fender?
This came through for a standard service and proved to be quite a nice amplifier; absolutely full of facilities!"
