Crusty McIntosh 2205 Restoration Time Lapse

[@Kakuro-hl1kk]

A shame to let such a first-class device go to waste. It's nice to see that an expert has restored the device to perfection. Thanks for the nice video. Many greetings from Germany.

As a Master Auto mechanic who has to wear many hats in my field .I do appreciate your technical skill in electronics ,the restoration of that Mac AMP was impressive to watch .

Thanks man, much appreciated.

As a McIntosh fan and proud owner, I salute you for bringing this artful beast back to life. Long may she run!!!

Doing all this work without damaging your wristwatch is impresses on its own !

[@craigm.9070]

Thank you for your time; incredible work to revive this great amplifier. It pains me that people, for whatever reason, allow these classic pieces to deteriorate like this. Rather than have a piece like this spend years or decades in a storage unit, basement or another moisture trap environment, sell it to a party that can/will restore it and save it. These amps are a beast; they don't make them like this anymore!

[@sonhouse9636]

Amazing modular design! What beauty! I don't know if what they produce now is as good quality. You have achieved a magnificent restoration!

[@MrBillblake123]

I loved this video. ..... It was EXTREMELY satisfying to watch. .... Thanks

[@richardhuston2426]

I enjoyed watching your restoration. I have the same amp, serial # AX6947, that I bought Aug. 10, 1978, probably just a couple months before yours was built. I have it serviced about every 10 years and last year I had LED’s installed that I now regret. The left side of the left meter is noticeably dimmer than the rest of the meters and the tech told me he can’t make it brighter, something about a white reflective material that doesn’t stay in place. That’s the only flaw with this amp now, otherwise it’s pristine.

[@vettemaniac2237]

Straight out of Binghamton ... Beautiful job.

[@scottb5662]

I was the DJ at a party in the 80s. The amplifier was a MAC 2205 built into a system at a pool house. We rented a large pair of JBL speakers. That amp loved it.

[@randallcromer66]

Awesome restoration of a even more amazing power amplifier, you sir are a true miracle worker...💯👍

[@danhorton6182]

Nice work! I like the final look. This year I’ve restored three MC2125s and I too recommended to every customer to leave that tacky plastic bezel that goes around the meters off. I sent them pics and they all agreed, looks much better with the plain glass.

[@skysurfer6870]

Absolutely Beautiful ! You did a fantastic job. I need my old Marantz 2325 recapped but still rocking after all these years.

[@SirBunghole]

I am glad you left some patina on the chrome and didn't go for a rechroming. I wasn't sure about the blue filter caps but they do compliment the meters and actually work out nicely.

[@danamcreynolds9456]

Thank you so much for doing this and showing your work. I have one that will never see this condition unless a world war comes to my neighborhood. I may be in the minority, but I prefer the meter bezel. I'd buy the one you removed if it's presentable.

[@BobWilson84]

Thanks, I kept the bezel for my spare inventory. I kinda like the bezel too, but most guys want them removed to look more modern. Have a good one!

[@renotsttam]

I recently acquired an early production MC2300 amp, it’s unfortunately in somewhat worse condition than this unit. That heavy rust that is somewhat contained to one area tells me that it was urinated on by an animal at some point. My 2300 was unfortunately stored face up with the back panel on the ground and something pissed on it collecting inside on the rear speaker terminal area. The whole rear panel is rusted on the inside and has spread to the steel side panels. It’s salvageable, but I’ve got quite the project ahead of me. Thank you for posting this though, it’s motivating to see the results.

[@BobWilson84]

Sounds like a fun project! Honestly those are more fun than typical repairs!

[@SylvainThuret]

Beautiful. Right now i unplug, open the chassis, take my vacuum cleaner, then I put quite a deal of electronic Spray and then use Q tips to manually clean the PCB and stuff. Im no electrician so thats my limit. But I see different cleaning technics here. Would love to have advices on how to open and clean safely my amps and cd players. Take care.

[@BobWilson84]

Hello, above all else, take a few courses on basic electricity. Learn ohms law, learn about power supplies, and learn about working around high voltages. Some amplifiers will hold charged capacitors for days, and they can pack a punch!

[@Mattospianos]

I noticed the same when I replaced the bulbs with LED's on my C26 that some parts of the display lit up brighter than others. I'm guessing this is unavoidable?

[@mazdef2001]

[@harrisfogel6992]

Wonderful! I wondered if you upgraded from original light bulbs to LEDs for longevity? I assume there was some paint work involved, although not pictured.

[@williambravin1254]

I have a 2705 and i tried to have a professional do the work unfortunately the LED did not last long (even with a powers adapter)

I installed new LED bulbs in the Mac, maybe I missed that part of the video when I did the editing.

[@kennym5898]

I know these amps are legendary, I heard one recently through some Harbeths! Question is, what is it that makes them what they are. Components, circuit design?

[@BobWilson84]

All of the above. They have a sturdy power supply and an amplifier design that utilizes transformers for impedance matching. I think another key is the rated output, the amps barely break a sweat even at loud levels which gives the amp plenty of headroom for large impulses.

It's almost a sacrelige to see a Mc2205 in that condition! Glat that there was someone with the knowhow and skill to restore it.

[@dandinhofer9240]

Nice work. However, it's a shame that with all that disassembly of components the job didn't entail taking it one last small step further and have the chrome chassis base replated. Why? cause as soon as that amp re-enters back to the humid environment that produced this oxidation in the first place, it'll start eating at the metal again - but now even worse than before since the protective outer layer was removed. The cancer thus resumes where the pitting was present.

[@johnbrewer2206]

Never used Deox-it D5 (red can) on a carbon pot as you did. The D5 spray has a cleaner that dissolves carbon and will kill the pot and can cause issues with the amp. You should be using the green can, F-5 or F-100 any of the fader lubes on those VRs or pots and your set.

[@BobWilson84]

I’ve heard that before and some of the techs I know also say to use the F5 on carbons. I’ve used D100 and D5 for years without a problem, maybe I’ve been lucky. But thanks for the reminder, I’m going to order the F-5.

[@ThierryMennechet-s7b]

Du trés bon travail mais franchement j'ai eut ce 2205 pendant une année avec un Mc C26 et un Counterpoint Ca 5000 les préamplificateurs était trop doux, pas trés vivant tout ça, un manque de dynamique évident, avec un Conrad Johnson seven premier c'est bon mais bon pour moi c'était décevant au niveau du rendu sonore, il y a bien mieux pour un prix bien plus abordable. Il lui faut vraiment un préamplificateur trés dynamique.

Very good eye! This amp was serviced sometime in the semi-recent past, and the insulators were not original. I made a judgement to leave them as-is. The paste wasn’t flaky and the work was done neatly. I think it was serviced and then stored in a damp location until now. Great catch!
