Amp showing its age?


Before getting into details, just the bottom line: can an SS amp, well into its second decade, begin raising its output impedance and/or dropping its peak current capability? Because mine certainly seemed to be doing one or both, so I have just replaced it, and now the speakers are again obedient.

If you kept it as long as you did, it can’t have been bad. It might be worthwhile having the unit serviced and bad caps replaced along with anything else needing replacing, As a second system amplifier it might be a familiar and welcome value, it seems as if it was very well made to have lasted so long.

@chenry  Makes total sense and no doubt you are right. Thanks, I will look into that.

Yes parts especially capacitors in the power supply section can go bad and need replacement.  Good news, there are probably better supply caps now and they will improve the sound of your equipment.
