Printed Circuit Board # 7
Bare Printed Circuit Board, ’48 Special – Tube Amplifier for Guitar
The AWA ’48 Special is inspired by the Fender Champion 5C1, which was built between 1948-1952. It makes use of a 6SJ7 gain stage and a 6V6 power amp. The preamp can use grid-leak bias or cathode bias. The ’48 Special is quiet and employs a large amount of filtering on B+ and offers the possibility to reference the center-tapped heaters to the 6V6 cathode. When cranked up, it breaks up nicely and produces about three watts into four or eight ohms.
The 5C1 circuit was substantially different than the later 5F1 Champ and 5F2A and today many players prefer to have a 5C1 in their studio, if they can afford it! The ’48 Special is a very nice circuit and the PCB is well done.
