MC-40 vs. MC-30?

[sloober]

Found a MC-30 on CL for a good deal. Had my AK friend Audiodon go get it. Turns out it is a MC-40. How do they compare?

It was the next generation design from the MC-30s, IIRC, Sloober. This would be the single version of the MC-240, of course. Differences: SS rectifiers, for one, slightly different tube compliment for another but very similar circuit topologies.

Cheers,

Well, if I can't find a replacement chassis, could I use this 40 to build an MC-30 on a new chassis? As said the tube compliment is nearly identical, so the transformers may be the same. They do have different numbers on their decals. John

sloober, I have read most people prefer the 30 over the 40. But you ought to listen to the 40 for a while and see what you hear. I have had a pair of 40's for about 4 years and really enjoy them.

I was thinking about your 40s when this topic came up. Unfortunately I've never heard the 30s to form an informed opinion of the comparison, but the 40s sound very sweet.

Thanks Sam.:thmbsp:

With only the one, it's gonna be a tough listen. Plus I need to restore it first and consider the chassis options. It looks crappy. I know, Pics to come.

Is the circuit design of the Mc40 exactly 1/2 of the Mc240?

 

[sloober]

I think for the most part. The output TX should be the same, but I was told the wires from it may be the wrong length.
