Re: Fender '63 Reverb Unit (Reissue)
Well so far, klent resultat av letandet i mina gömmor efter mod-beskrivningar...
Tills letandet gått bättre, två (för mig) klargörande "how-does-it-work" resurser:

Another tube swap that may or may not be of interest is substitution of a 5751 tube in place of the standard full-gain 12AX7. One member reports that this was tried with a tank with a MOD pan and full-functionality was retained, although some additional "chiminess" was present that wasn't before, as if the Accutronics tank had been re-installed. This is a subjective tone judgment obviously, however, those who keep both pans around for various situations may wish to experiment. If the simple swapping of the tube that performs the mixer & tone functions changes the tone sufficiently, it may be more convenient to simply change the tube rather than pull one pan & re-install the other. It may be that the 12AX7 buffers too much of the dry signal (and its highs) resulting in the "tone suck" condition mentioned above. Perhaps the 5751 - at 70% of the gain of a 12AX7 - doesn't buffer the highs as much as the regular tube. (Comment regarding this from a competent tech with reference to the schematic would be welcome.)
