The AB1270 schematic, which my PR goes by (although it was made a bit before December) shows a .002mf (2000pf) cap in parallel with the 220K resistor at the reverb footswitch jack. What is the reason for this cap? The AA1164 schematic doesn't have it...
Also, after poring over the schematics, it seems that the only differences in the AB1270 circuit and the AA1164 circuit are this cap, a different value cap in the bias cirucit (50uf/70VDC, rather than 25uf/50VDC), and that a couple of plate resistors are changed from 100K, 1/2 watt to 100K, 1 watt. Am I missing anything else?
What would I gain by changing these components to the values in the AA1164 circuit?
