McIntosh MC2102 Question

Recently doing some reading on the McIntosh MC2102 tube amp. Read on one site that MC2102 flamed 2 or 3 tubes and that early versions of this amp had some problem. Anyone familiar with such a problem or just an isolated incident (urban myth)? Thanks!

I think the problem was with the tubes, not the amp's design.

I have two of these amps, running mono/bridged. This amp beats out all contenders at, or quite a bit above it's price range.

Great amp!

Oh, tube rolling is lot's of fun on this amp.

Mac has changed the bias on the 12AT7 drivers to increase lifespan. I don't know the S/N cutover. This is documented in the service manual.
