McIntosh MC-75 unity coupled output transformers

[HeeBGB]

Ok so my son recently came to
Me asking for help in building a HiFi rig.
I have always wanted an old McIntosh MC-275 or 240.
I set about trying to find a source for the unity coupled output transformers.
I found a winder that has done it before and is willing to do it for me BUT I need to order at least 16 pieces for him to order the materials needed. I assume he has minimum orders on the materials and needs to move at least 16 to make his profits. I do not have a price per unit from him yet either.

SO my question is.....Is anyone here interested in a set of these transformers they would be suitable for an MC-75 or MC-60. Again I do not know the price yet and I don't want to bother the winder unless I have the ability to move 16 units. So if I have interest I will persue him for price per unit.

Please PM me if interested

If I am not able to get the McIntosh iron I will probably end up building a Dynaco ST70 clone

Mac transformers are quite unique, and had to find, if any.....
I have seen refrences to a US company supplying transformers, and spare transformers should be possible to find, maybe from McIntosh direct, but maybe not without aproper serial number......
You've gotta get googlin'.........

Did you contact Chris Merren at merrenaudio.com ? I have a mac 60, I'd love to build a mate for it someday....

I'm sorry - I didn't readd you post thoroughly... I might be interested.... but I suspect the price will be ugly....... There's still very good transformers out there for the more traditional designs of UL/PP...

Chris Merren is the winder I have contacted. He winds the MC-75 output transformers and says that the specs are the same for the MC-60 outputs.

By all that I have read the McIntosh amps are not all that out of the ordinary aside from the unity coupled output transformers. My plan is to build a couple of MC-75 clones or an MC-275. So if there is interest there may be a group chassis build for this as well.

I just need the 8 or 10 people willing to go for it and then I will approach Chris Merren

Looks like a lot of fun building one of these.
