The DC bias across this cap also helps out with its being an electrolytic. While a film type would be better, size is a problem. Replace with same type and add a 0.1Â♟ film bypass.Ĭ309, 310 are the output coupling caps for the pre-driver section, 10Â♟ 25V. It is a Mylar type so it is likely to be OK, upgrading it to a Polypropylene type with give a smoother sound to the high end (0.47Â♟).Ĭ307, 308 are emitter bypass caps, 100Â♟ 15V. The sound would benefit greatly from replacing a few dried out electrolytics, and adding a few film types here and there.Ĭ301, 302 is the main input coupling cap. In Reply to: Re: MC2105 $ 100 even 20 yrs old is a best buy for me. This list is for the MC2100, electrically it is the same as the MC2105, just without the meters.Įven though your old amp is still working, you have no idea how much of the music you are missing.ĭigi-Key is good, Mouser has no minimum order. The first thing I would do is replace all the electrolytic capacitors. The MINIMUM age of a MC2105 is 30 years old. I can't do it & I don't want to wait for repairs. And I don't want to get something that needs work. You put a deposit on them & then they restore it. I checked with McIntosh Audio but their tube units aren't ready to sell. It's a lot of money but I'm tired of looking. So there cheaper brand new from McIntosh than used? LOL. He's holding it for me & discount or not I plan on getting it there tomorrow. I asked about a discount cuz it was a floor model but need to call back tomorrow when the manager is there.
Said it was only hooked up a couple of times. Then I called another dealer & he has one on the floor. Said he'd put me in the next group of backorders. Surprise! $5500 brand new! I called one dealer & he had them backordered with all of them already sold. Than I thought "Why don't I call local McIntosh dealers & see how much they go for new. One was going for $5499 & the other for $5777. Thank You for all the replies everyone! Well, after flip flopping all over the place! Tube, no SS, tube, no SS.
