B104A Amplifier PCB with NO components for Chandler Germanium Pre

Category:

Product Description

Amplifier PCB with no components fitted based on the B104A by Rupert Neve this PCB can be used to repair Chandler Germanium Pre’s in place of the potted module that cannot be serviced. This is the same circuit as used in the original potted module apart from the input transistor which is a BC847C as a slight improvement in noise specification over the BC184C.

This design should be an improvement over the original as it is not potted so heat build-up is reduced and serviceability is introduced for future maintenance.
