Carver m500t buzzing

So there is a local m500t for sale. Owner says selling for a friend who passed away. Advises it makes a buzzing noise and goes into protect. Seller also adivses may see some resistors blown inside and or kids hooked it up wrong.

Can anyone here help me trouble shoot if I bought this? Cost is 100 bucks.

Any schematics around I can use ?
I have a soldering iron and some electronics exp building crossovers etc... I am not a totally noob but Im no genius either :)

edit: I found the schematic online
edit: is should put this topic in repair!

BillD is the undisputed "KING" of the 500t, however he is currently unavailable to help you. If you are technically inclined I'm sure someone on here can assist. Start by getting the service manual....http://www.carveraudio.com/index.php/ma ... 0&start=20 P.S...WELCOME!!! =D> =D> =D>

I can't help with the problem except to suggest that you grab it & send it to Bob or Rolland. They will refurb it for approx $300.00.

You will then have a "new" M500t for a little over $400.00

A Deal !!

thanks... i took a look over this and does not look to bad.

do you or anyone have a couple steps to start to troubleshoot... the main things to isolate the issue ...etc.

also... what would make it unrepairable at the DIY level?

i'd love to send it to carver but I'm on a budget ;)

PS got the seller to 75... more interesting price

Why do you say that Jesse?

If he can get an M500t with a hum/buzz or someother failure but at $75.00.

A trip to Rolland and $300.00 or so will result in a completly refurbed (and possibly upgraded) M500t.

Normally I would never disagree with you but I have to ask this time.

Re: Carver m500t buzzing

If the cosmetics are good you could flip it on eBay "as is" and make a quick $75-$100, possibly more. Even refurbished the m500t seems to top out in the $450-$500 range so from a purely profit motivated stand point the "quick" sale, let someone else deal with it would be the route to take. If you want the amp around for a long time, send it in for a complete go through, you'll still end up around the average "used" price for a fresh model. My .02 8)

Frankie, you can disagree with me anytime you want. 8)

I say it because unless you know exactly what is wrong the risk is too great. In this case he doesn't know exactly what is wrong, does not have to skills to repair it if he did nor does he have the money to send it off for repair.

Merry Christmas,
Jesse

True that.

Plus, if the transformer is shot then he would have a $75.00 doorstop.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.
