Nortronics heads in an MCI JH110 mono to stereo conversion

Hi All,

I have two MCI JH-110 -inch machines, both mono, saved from dumping, so cost me nothing.

Also I have acquired Nortronics -track medium-impedance "premium" Record and Repro heads: I'd like move one electronics block across from one 110 machine to the other to create one stereo machine.

I'll retain the original full-track erase head, since I will never have a need to re-record only one track.

Are the Nortronics heads a good match for a JH110?
I have found posts that say mechanically they fit pefectly, but no comments on their audio performance or how they match the MCI amplifiers.

Any ideas, or suggestions please?

I purchased a pair of Notronics heads for my MCI about 10 years ago from one of the original Nortronics guys. He told me that the heads that he was selling me the should be drop-in compatible with the originals. But do you have the same heads as I purchased? Who knows...

Unfortunately this is one of many projects which I have never had time to get around to, so I can't tell you how it worked out. Unfortunately I can tell you from experience that the MCIs have hundreds of those little red devil caps which love to fail short, and fry resistors. So I recommend replacing all of those before doing anything else.
