The reason I don't think it is the tape monitor switch is that he did say that "both channels are available" when the switch is set to the "A + B" mono position. This would lead me to believe that the channel that is OUT (left channel) in the stereo position is getting through the tape/monitor switch to the blend switch. It appears that somehow the left channel just isn't making contact when the switch is set to the full stereo position.
Been away for a while and only until just now can grab a can of SOB electrolube and cleaned the pots. Problem of only right channel can be heard when blend switch is at "stereo" is now gone.
Referring back to the picture of component values of PC-5 curcuit board that you kindly provided, and compared it to my PAS-2's PC-5 board and noticed a difference. As can be seen in the picture below, the CIRCLED two components on the board are resistors, while in the PC-5 circuit picture, that spot are shown with capacitors of 1500pF. In fact, I've also seen pictures somewhere showing resistors on this location of the PC-5. Is it that the picture (from www.tubes4hifi.com) of PC-5's componemts valaues represent a modified version of PC-5? Should I keep the resistors or replace them with capacitors?
Furthermore, it looks like that all capacitors of the PC-5 (in fact, same for PC-6 board) of my PAS-2 have been replaced because they are not the stock "black" ones, as can be seen from the picture and most of them are not of the same value as indicated in the components values picture, like
0.004uF in place of the 3900pF
0.02uF in place of the 0.22uF
7500pF in place of the 68oo pF
Do I need to correct this by replacing them with capacitors of the correct values?
Another question is there is a disc capacitor at the bottom of the chasis, as shown SQUARED in the bottom picture. Could you tell me the type and value of this capacitor? Thanks very much in advance of your help.
