    MC352 (mono) vs MC452

    If I remember correctly after the 352 they changed the part # but it looked the same to me?? I would have to talk with someone else in the service department to be sure.It was hugeomungus.

    MC 452/462

    Okay I left the Mother Ship 3 years ago. The power transformers were made by Schumacher in Illinois for many years, then they moved production to Mexico and were Schumex, can't remember the year.I believe the Mc352 used the same power transformer as the 452 and 462,over built like most Mac...

    Best looking McIntosh component currently in production (picture poll)

    Not in production anymore but when I saw about 30 of the gold color chassis MC 75 rolling down the line together it was a beautiful sight, they actually use the same power transformer as the MC 275 .The 901 was so big they had to make a completely new line to build them on...

    C20 Transformer Tar Leakage

    There's more than one way to fix that. That was potted before I started there. Sometimes we would cut the tranny out and re pot them rather then scrap the whole thing. No where to hide it if I made the mistake, some of the cans were like a quarter inch higher than the other. Six AM I didn't...

    C20 Transformer Tar Leakage

    Lot's of ways on here would work.The tar pot is set at 450 degrees, the flash point where the tar will burn is around 600 degrees. I potted quite a few in the wrong cans when I worked there,its really messy trying to get them out, good luck..

    Paradigm Studio 60 V4 vs. NHT 2.5i...upgrade??

    I have owned the 2.5i for quite a while it is designed by Ken Kantor I find them superior over any Paradigm I have owned.I drive them with a B@K Reference 202, 225 watts into 8 ohms 75 amps of current.The design eliminates side wall bounce in my narrow room.The Bass response goes down pretty...

    MC451 half of a MC901

    The Mc 206 was in production when I started potting transformers,I think they used the same can from the previous model,so I had to shoe horn it in the can,I would put a inch or 2 of the molten tar in the bottom of the can and ease the torroid down into the can and hope the tar wouldn't flow...

    MC451 half of a MC901

    TWiiii, I remember potting the Mc206 Torroids they used such a small can I could hardley get any tar to flow around the Tranny.I was happy when they switched to the Mc207..I pretty much pottedd all the transformers and autoformers from 1999 to 2020 ???

    McIntosh XR240's

    My 30 year old pair of XR240's that I got for $250 and refinished have very good Bass but the top end is soft sounding.My other speakers like my NHT 2.5i are bright,thinking about re capping them,they don't image or sound stage like they should either.
