RE: Need MCS 3245 power supply repair help/advice

May I add? To spend ANY amount of money on this unit is of questionble merit, but I also understand FULLY the importance of "sentiment"- if it is THAT important, then spend as much as you can afford.... I suspect that you will smoke that same ps filter board instantly though... so get a variac and ramp up the 120 Vac slowly while monitoring the o/p voltage (speaker terminals) and stop the instant you see ANY increase in DC voltage- I'm betting the o/p transistors (one or both channels) or the driver transistors are shorted... so don't go too far down the trail unless it's that important....
