    It looks like the newer models like in the 2015 schem. from same post already have the reverb revision all taken care of?
    The version of the YCV50 service manual I referred to for the reverb wiring is called smycv50blue.pdf. In that case C7 is fed direct from pin 1 of U2. But I just noticed that in other versions C7 is fed by pin 1 of U1 and with a resistor and cap in series. I wouldn't be surprised if that would have had a bearing on the feedback I was getting with the reverb pot cranked up. The revision number for my actual PCB is 10.1 which is virtually identical to what is shown in the sm_ycv40_M581-7.10.pdf manual. If you look in that one you'll see that C7 is fed from the same source as R63 (pin 1 of U1 with a cap in series.)
