Carver PM-175 Opinions Please

Post by chains91 » Thu Feb 20, 2014 8:43 pm

I've never owned Carver gear but recently came across a PM_175 power amp at a pawn shop for 110.00. I put it on lay-away on a whim with no knowledge of it. I don't see any useful reviews online and was hoping someone would chime in with their experiences or opinions on this unit. Thanks

Congratulations on your new amp!

The PM-175 seems to be uncommon these days. I don't know how popular they were when they were being made back in the mid-'80's.

I haven't seen what they look like inside, I'm sure we would all appreciate any pics you could post!

I haven't been able to find a service manual or schematic, but *think* the PM-175 was a "one flat board" amp. Pretty sure it's a Mag Field amp, with two rails for the output stage. Possibly the pro version of the equally-rare M-0.5t?

The PM-175 was rated 175 Watts per channel into 8 ohms, stereo. It was also bridgeable in series mono with a switch (common ground outputs). Non-inverting in stereo mode.

As were most amps of that era, the XLR's are factory wired for pin 2 *cold* (-), although many were subsequently changed to the modern standard of pin 2 hot. The TRS jacks are conventionally wired and parallel the XLR's (easy to jumper for dual mono or daisy chain).

There's a provision on the back for changeable modules, such as crossovers. Might want to see if it's got something special plugged in there!

Good luck!
