Adcom 7300 Problem - Power Supply?

ODougbo · 07:54 PM

Co Worker's Adcom 5 channel 7300 amp stops playing (all 5 channels) after several minutes of operation.

After it cools off for a little while, it will play again, but for a shorter length of time.

They had had it for a for 7 years; never played it above a whisper.

Is this a power supply problem?

This looks new on the inside..........

Any ideas why it would shutdown after a few minutes?

Maybe should send it off somewhere.

I don't know my friend was talking about, the amp works fine.

Nice sounding and powerful. I ran it all day with 2 - 4ohm subs 2 - 4 ohm satellites. It hardly got warm.

Very nice terminal strip in back for the 5 speakers wires.

btw, we found the amp 1/2 price for some reason, it was only $350 new-in-box

The amp weighs a ton :-/

Intermittent faults have a tendency to temporarily disappear as a result of transportation, vibration, or any other thing than just sitting somewhere.

Try it out for a couple more days...

Don't think I be giving this back anytime soon, it sounds great. The speakers are jumping, the bass is flowing like water. The 2 - 8" woofers are 8ohm, one on each channel (iso tunnel).
