Hi,
I have a unit for repair that another service person took the transformer cores for the MPX section to prevent anyone else from repairing this set. So what is actually needed is just the MPX section, or even just the transformer cores. I would prefer the entire transformer if possible. I'm not marking this up at all, so whatever it costs is what my customer pays.
He is willing to pay for an entire tuner as long as it is reasonably priced. This will be shipped to the Toronto area where I am.
If we get the entire tuner, I'll try to carefully remove the cores so I know the approximate position they should be in and how long they are and make an honest attempt to repair the one tuner I have here without making the parts unit irreparable.
If you have a cosmetically damaged MR74, please consider allowing it to be used as a donor set with a possibility that it too may be repaired. Any shop with a bone yard, please consider selling it for parts at a reasonable price. If you are in Canada, I would agree to return the chassis with everything we don't use.

That’s just sick, who would do that? Did you check with Audio Classics? I think the tech’s name is Ryan, if memory serves.
Hi Dilbert,
Yes, and McIntosh as well. No donors available and no transformers in parts stock. The person who did this is in Mississauga and has a good following on CAM. He even set the IF strip to 10 MHz instead of 10.7 MHz! He claimed that all the the cores were broken. Three, one a lower core and two transformers involved. No evidence of a broken core anywhere and he did not return any parts.
The customer also had a McIntosh 2505 in and was charged for a new auto-former, but did have the defective part returned. He installed a speaker delay circuit with a little relay and modified the power supply so badly that it was touch and go there. I think I now have the right information to rebuild it as factory and solve the output offset problem.
So this entire story is really about a bad "technician" and one severely abused customer.
Anyway that tech let it slip t hat he has the same tuner, and I suspect he replaced the cores that he broke in his with the ones from this tuner.

I've got two MX-110 tuner/preamps sitting taking up space on the floor here.
Both suffer from major issues and will likely be sold off as parts units eventually.
One has a botched volume control replacement - no loudness tap.
The other's got Silver Mica Disease in the IF's.

Hi wiseoldtech,
Why is it that these hacks continue to do business without paying for what they did? It's always the customer, and the next tech that tries to help them out that ends up paying for their destruction.
Do you know if the MX110 is similar to the MR74 MPX section? It seems that I have to have another look at this tuner to confirm what I need. It's been over a year searching for parts.
