The carlsbro 100 pa/r amplifier
This is my first post.. I'm new to the land of valves really. Ive got a Calrsbro 100 watt Valve PA Head which i use for bass in a 60s/70s band in UK.. Its got a set of quad JJ's EL34s. Is there any tweek i can do to make it better for the bass. I aint touched the biasing ..It seems to be over driven, possibly without being that loud. As i only play with drums and guitar...I use Fender P Bass with Bareknuckle pickups and the amp goes though a warwick 2 x10" Looking on line today saw videos about changing caps/ resistors in tone stages. any help with biasing too would help... I only have a Multi meter.. I dont have an Silly scope or signal gen's
can anyone help ?
