Tube question for the electrical engineers
Did this also happen prior to your acquisiton of the MEN220? I'd take the MEN220 out of the loop and see what happens over a period of time. How old is the MEN220? If fairly new (within last 6-9 months or thereabouts), the issue has been resolved....

KT 88 types in Mcintosh's new amps?
IIRC, two different KT88 manufacturers actually -- if the plates have round holes they are New Sensor & if they have 3 square holes, they are SED.Bob

I stand by what I know which in this regard is fact.Bob 
mcintosh c-2300 vs mcintosh c500 phono section
The phono stages in the C500 & 1000 are identical to each other, whereas the C2300 phono stage resides on the motherboard & in the case of the MC stage, does not have an independant MC module.Having owned both the C2300 & C500 combo, t...

My SME manual states to replace the belt at 1000 hours & prior to that, it should never need cleaning.Bob 
Suggest upgrade from c2300 phono stage
Just to be informative -- the two shinny modules towards the rear in post #27 of the C500/1000 pictures -- those are the left/right MC modules which are non-existant in the C2200/2300's.Bob

Suggest upgrade from c2300 phono stage
Completely different in design and actual components. The fully balanced C500 & 1000 pre's have left & right MC modules whereas the MC circuitry in the non-balanced C2300 is incorporated on the main component board.Bob 
Suggest upgrade from c2300 phono stage
I'll add the phono stages in the C500 and 1000 series are identical and when comparing these two pre's with the C2300 on that aspect, the MC/MM within the C2300 is not even of same design/configuration.Big upgrade from C2300 to C500/1000 series.Bob 
Suggest upgrade from c2300 phono stage
I'd recommend going to the C500C/C500T in lieu of the C2300. Did that myself and never looking back. The C500 combo is down right quiet & had an awesome MC stage. Additionally, it is 99% of the soon to be discontinued 1000 series.BOb

Why do old tubes sound better than current tubes?
I picked up a few of the new Genalex 12AX7GENGP tubes from NS and did an audition over a weekend between them and the 04/60's Telefunken I was using in my C500T.Guess what -- even though still early, and the Genalex have only 5 hours on them or so...
