Nelson Pass designed those amps , so there's nothing wrong and much right with the design. Having the caps upgraded is not hugely expensive (if they need replacement). I think the pa7 was 200 or 225 wpc. All in all , very nice amps for the money now. They show up on fleabay now and then. You can almost always sell them for about what you pay for them. They are probably worth a shot if the price isn't bad. Good luck!
