Hi all. I've been running the little PS Model 2 amp for a while and it sounds pretty good when really warmed up: was wondering about possible improvements in the input signal path which is a bit 'cap 'n' switch messy'. I don't have the schematic but (as an old newbie) it looks to me that the input area could do with a re-vamp. Just from looking at the photos has anyone any suggestions please. Also looking at the speaker output area. Thanks, Mike.
