I've been restoring my fave Guild amp, the Thunder 1 RVT and have a few questions for other owners/users. So far I've replaced all electrolytics, re-soldered all connections, re-tubed and replaced speakers (WGS G12Q and G8C). It sounds great, except for the following:
1) Reverb Speaker frame connection: Originally I remember a wire connected to the reverb speaker frame. It is missing now and I don't remember what it was connected to or what it was for. Does any one know what it is connected to (speaker pos or neg)? Is it even necessary?
2) Hiss: The amp has an excessive/annoying amount of hiss. I also have a Thunder 1 and it has a lower (normal) level of hiss. Wondering if other owners have this issue or if there are any tips to reduce hiss (wiring, replace key resistors, etc)?
3) Tremolo: When I engage the tremolo there is a small volume drop and noticeble distortion when I dig into notes/chords. The distorion is not present when tremolo is turned off. I've noticed the same thing on my Thunder 1 and wonder if this is just inherent in the design or if its fixable. Does anyone else experience the same thing? or have any ideas for troubleshooting/fixing?
Mostly, I'd like to reduce the hiss...as I'd like to use it for recording.
Thanks for any info!!
