Carver M400 Magnetic Field Power Amps

pheonix358 · 14th March 2009, 04:56 AM

I have 2 of these. They are 240V models. They do NOT work. I am considering throwing out the insides and making cute amps using the cute metal work. Could be a nice 2.1 system for my computer desk.

Question, is this a sin. If so is it a big sin or a little sin

If anyone wants them then make an offer, I will post anywhere and I am posting from AUstralia. Cosmeticaly they are OK, could do with a spray paint job.

I just picked up a broken M400 and I may need parts.

Hi Pheoinx

These amps were well regarded, and designed by a very highly regarded designer.

Bob Carver was known for not following trends, and designing his way.

I reckon they are worth getting up and running, especially of they are the "T" model. The T model many say was much better.

Hope this helps.

I would drop the guts and put an Icepower or hypex module inside...or , if you don't need the power, a cute square Gainclone.

I was not a big fan of Carver amps. Lotsa power, but thin, anemic sound.

Damnit, you're far! I'd love to tackle the repair of these amps!!

For ***** and giggles, can you tell me how much it'll cost to ship 'em to M4B1P1 in Toronto, Ontario (Canada)?

I just repaired mine. and it wast that hard to get running. the power supply is basically a light dimmer! there are two 2amp bridge rectifiers in parallel for the 25V supply. I guess these fail often causing the unit to blow fuses etc. I followed the instructions in the service manual and the repair was quite easy. just a PITA to get the lil bugger apart far enough to GET to the dang bridges. I upgraded to a single 10 amp bridge rectifier and all was good after that. the service manual is well written and easy to follow.

I don't remember the M400 being an amplifier that had the "T" option. Does it stand for "tube"? Working there, we called it the Carver "tweak". Didn't see him often, though when I did, Bob was usually jubilant about his whatever it was he was brewing up. Besides the Carver challenge, professional amplifiers for the touring Michael Jackson were big for the company.

Wasn't the "t" designation for "transfer function calibrated"? I believe it was supposed to make the amps "sound" like well regarded high-end amps of the time period.

That's it! The shootout happened to be a test against a Conrad Johnson tube amp (another listening test occurred against Mark Levinson ML-2 monoblocks).
