Prior to the replacement of all the said tired and duff bias components.

This photo is actually of the reverb version….hence the five small controls rather than just four. As there were some knobs missing and some wrong….I replaced the whole set with nice looking retro ones! (Please note, at the time, I was out of stock of the smaller matching ones….hence not shown on this photo).

A good few new components replaced.

As-in most cases of this kind of design, the main board has to be removed to allow access to the soldering underneath.
