Did you re-chrome the chasis and paint the x-formers?, posted on December 16, 2014 at 07:34:29
DFaulds Audiophile Posts: 616 Location: Northeast Ohio Joined: October 19, 2000	The reason I ask is that I've got a line on a pair of these in really bad shape that would need a complete overhaul. I'm pretty sure that Audio Classics does this, but I can't even imagine what they would charge.

(I have never did amps but have done touch up work on cars. I put the cans in warm water so the paint flows better. Dave

This isn't the kind of thing I had in mind when I commented about Mike and others improving on the work of Sidney Corderman and Stew Hegeman. These are updates with components that were not available at the time the amp was designed and made. Nice job!

And did he also do the re-chrome?, posted on December 16, 2014 at 11:20:57

Actually, Sidney did and perhaps does. Last I knew he was still living and active in the business. I believe he was involved in the Gordon Gow edition of the MC275, which uses modern components. I am not sure of the extent to which he was involved in the Frank Gow C2200.

In former times I knew Sidney and many of the McIntosh people, especially the Gows, father and son. Frank was a guest at our wedding.

These are what you call McShane's done to the limit,pretty much the way I did yours.These have tube rectifiers and you have Schottky diodes and 35uf film cap bypasses in place of the extra decoupling capacitance on each section..

Oh there is no comparison..The mc60s even running EL34s which runs them a bit cold unless you change a bias resistor has more character and more detail and more depth than the 8B does..I have a pair of nines that I left original and they were given to me by an old audio mentor that bought them new in 1963 but they never impressed me..I've owned them since 1992 and I just left them alone because there isn't much room but I will recap them..
This is the way you do vintage gear as I did the Mc60s because this way I can put it back to factory stock without damage.

All three of those tubes do very well in these amps. "For every complex problem there is an answer that is clear, simple, and wrong" H. L. Mencken

Hi Mike,

Interesting! The circuitry is very complex. It also could be the unique bifilar output transformers. What is your opinion on why it sounds better than the Marantz?

The mind is a unique thing to have and the way you use it. It can make you believe anything if you let it!

With that said what does looks have to do with sonics except for the fact that if it looks good it will sound good? In some cases yes, you can convince yourself that the appearance is part of or all of the sound, forgetting the parts inside help to make up the sound. In some cases an ugly amp or preamp can sound awesome because it has nothing to do with looks. It's the way a circuit is implemented and the parts used to implement it.

Now with that said most good sounding units also look good. As well as putting the time into the way something sounds the builder or manufacturer will also make accommodations for aesthetics. Sex sells and it has to catch your eye before you give a listen.

I had one of the ugliest 26 tube preamps ever a few years back. It sounded great!

Crazy Dave Audiophile Posts: 14371 Location: East Coast Joined: October 4, 2001	I actually like it when a butt-ugly piece sounds good. I have a Van Alstine that (IMO) fits that description. However, I agree that usually, if the go to the trouble to build it right they also try to make it look good too. Dave

I remember Bruce Rozenblit writing in one of his tube audio design books that the MC-60 design "humbles the best of us." Cathode windings that apply degenerative feedback, plates coupled to the opposite tube's screen grid, bootstrapping in the driver circuit, and a bunch of things I'm probably not remembering. It was all seriously cool for 1955... and for today.
