Help with McIntosh Repair Facility


My MC452 is having an issue with the right channel that's a little weaker than the left.  Not by much but definitely noticeable.  Have been trying to diagnose the issue and everything so far points to the amp. I'm using XLR and have changed ICs , preamp tubes, cleaned amp inputs, etc.. but the head scratcher is if I switch the right and left IC inputs on the amp the sound or output is balanced. The meters are in alignment as they should be. The only issue is of course the right and left channels are opposite now.   I've spoken with an authorized repair center and bench testing is $350 and worse case scenario the board needs replacing plus labor can hit $2500 which in my opinion is ridiculous.  Has anyone experienced this issue or have any ideas or know of a reputable or more cost effective repair facility? I'm in Lexington KY.  Thanks in advance.

That is some expensive bench test. A test to give an estimate is normally 130-170.00 on the west coast. Sometimes it refundable, if they can't get to you before 90 days. It is still applicable to the total cost.
350.00 is WAY out of line and a 2500.00 est before looking. Geeze ship to the west coast it's less expensive. That guy is NUTS. 350.00 for look see. He ain't a peep show and he sure ain't a Roquel Welch..

He does have some BALLS for asking those types of prices though.. Give me the guys number. I'd like to call him and tell him he is WAY out of line on his prices. Most Mac repairs are under 500.00 + shipping. I've NEVER heard of a 2500.00 labor charge or parts for that matter. New trannies too boot.. Good Lord.

You called the wrong guy, Jefe.

Switch which inputs? You mean to another input or left to right? If left to right inputs cables fixes anything, how does that equal to an amp problem if ANY cable change fixes it. For some reason either I’m not understanding your description of the problem or the problem is a cable. What is the source?

I’ll say it again 500.00 is the norm for a Mac repair. With a transformer add 5-700.00. IF more than one failed I’ve never seen that either.. 50 years with Mac for me.. Currently 30-35 pieces of Mac gear I’m running lowered stock these days. :-)

Is there a RCA vs XLR switch, in the mid position or WRONG position, some weird thing like that? There is no frayed cable or any broken "LOOKING" cable. Input or speakers, not a single strand of wire anywhere is touching?? You ran YOUR hands overs every cable with a cotton glove. It will snag if there is a problem. A pair of cotton gloves is pretty cheap..:-)
