These suckers are old and may need some attention to get them back to factory specs. There's another thread down the page a bit (mc250 DIY Rebuild) where I talk a bit about my recent experience. I'm lovin' my rig now-
PRS w/dallen pups, OBEL, Waldo buffer--> sms Jer pre --> Mc250 --> 2x12 K120.
Enjoy your amp...let us know how it goes.
What he said. I have a very road worn 2105 that was my bass amp in high school in the 70s. It was trashed then but sounded great. However, over the years, the sound slowly degraded until I brought it to a gig and realized that it sounded really pretty bad. I brought it to a local tech who has worked on these things forever and $250 later, it sounds amazing once again. Now it powers a pair of ProAc Studio 100s for my home studio. It's a match made in heaven! These early Mac solid state amps really do sound amazing when they are completely in spec. I've put it up against a few modern power amps using Tannoy studio monitors, Crown, QSC, etc., and for pure fidelity, there's no comparison.
The tech also went over my MC30s. I never believed the hype about hifi tube amps before, even with owning these things for almost 20 years. Now I am a full on convert. These things are positively 3 dimensional. He also had a quad of original McIntosh branded 6L6s that he sold me for $100. They sound good, but I have to say that the Philips 7581s I got from Fat Willie, aka Lord Valve, sound much better. I'm going to try the Mac tubes in my Showman.
But I digress. Long story short, get it all recapped and checked out, plug it in and enjoy. You should get 20 years out of it before it will need another service.
