Some of you may have seen my thread regarding my conversion of a Blues Jr. from a combo to a head unit. Just wondering on how I relocate the reverb tank during this process.
Should I fasten it to the top of the head cab, or place it directly on top of the chassis?
Will there be noise/interference caused from the tubes or other components?
Will there be enough room to keep it away from the tubes so there isn't any heat transfer?
The main point to keep in mind is keeping the sensitive end of the tank, the end that is sending the signal back to the amp, on the opposite end of the enclosure as the power transformer (for hum reasons).
I once put the reverb tank under the chassis. I cut a big hole in the wooden enclosure such that the tank fit in it. Naturally, since the tank was thicker than the wood, I had to make sure that the tank, which was now protruding into the chassis about a half inch, did not contact anything in there. I put a shielding plate on the bottom of the enclosure to shield both the tank and the chassis. Not sure I would do this again, it was kind of a puzzle.
Don't forget that the tank probably has to be mounted in the same orientation (relative to the local gravity field) as it was in the combo for best performance.
Good advice above on location (end to end) and orientation. Many heads with reverb are taller than those without. I assume that you can making your own cabinet for the head, so allow enough room. You might want to consider getting the pan out of the bag. The original Fender standalone reverbs units from the '60s have the pan mounted on springs.
Those units have a pan that needs to be mounted "vertically" and it is on the front panel. You can do the same with a pan that mounts flat on the bottom of the case, like this.
