Hi all.
Thanks TrungT.
A very informative and fun to watch video.
May I just say that I don't like the idea of the green lights under the small tubes (More like a gadget and a show off)
and the big PCB (I hate PCB)
and tar in the transformers casing,
which makes them unrepairable, they become throw away things .
Other than that, it's a nice looking unit.

Cheap parts throughout. I suppose folks like us are not the target audience.

That's not your daddy's McIntosh. I have worked on many of the originals which are all hand wired and easy to work on. This is a nightmare to fix. You cant get to the underside of the board without disconnecting the transformers.

BTW the transformer laminations are not carbon steel but silicon steel. Carbon steel is hard and for drill bits. I note they use tar and don't vacuum pot. The output transformers look as they have been simplified from the original winding spec which Sao Winn gave me.

Did you see all those surface mount ICs on the board? If Frank  Mc Intosh was still around he would have a fit. g

Fun to watch however.

Hi Roger.
When I look to purchase any kind of products I always look at how easy the service can be done.
That's why I hate PCB and crowded under the hood stuff.
The same thing applies for the professional photographic flashes I sell.
I even refuse to sell a particular model from a company I represent,
if it's too difficult to repair.
Today PCB is way too common...

Well stated.  I never have been a fan of mounting tube sockets on PCB's.  The old 275's are not that hard to fix.  The quality of the old transformers was better.
