Correction: it is a '77 SF Twin Reverb in for a cap job and blackfacing. This one is close, but not exact to this schematic. It has two 100uF/350v reservoir stacked caps, the attached schematic shows 70uF. Does anyone see an issue using 80uF here?
Also, the reverb drive tube has no cathode bypass cap, just a 820 ohm resistor, the schematic shows a 25uF cap and a 2200 ohm resistor. Should I go with the schematic?
The second cathode on the trem tube has a 5uF cap, should I change it to 25uF?
The bias supply has two 80uF caps separated by a 3.3K resistor, why was this done, and is it a good thing? I am going to change the bias control back to blackface and lose the balance thingy.
Any other recommended changes?
