Hello

That is awesome. I don't know if I would power it up without speakers connected or a dummy load. That seems to be a topic of debate. On such a high dollar item I am not sure I would be willing to operate it without a full recap. Of course if you want to make a quick $$$$ and ship it overseas I would do nothing to it but take pictures and ship it. Many collectors in Asia would want it in original condition. Thanks for sharing!
 
How do I put larger pictures in the body of the message, instead of thumbnails?

Their might be an easier way but how I do it is have my pictures in a online photo hosting site, and then you just copy the URL site for the picture you want to post and copy and paste that URL into the body of your message. Their are many sites that host pics, and many are free, I use photobucket. Also if you some reason your PC crashes and you didn't have it all backed up you won't lose all your photos. You can also share them with people or family if you want so they can see your albums.
 
I trust you have speakers or some dummy load on those as you make the tubes glow? I'd hate to see you let out the magic smoke.
 
Here are some pics of the McIntosh C-108 that came with the console unit. I also am posting a few pics of the maual and the little "cheat book" that came with. It is full of recommendations for different record manufactures and other setup info. Alot of the same info is in the manual along with good info on setting up the unit and some good info on maximizing performance and some things to avoid.

From the looks of it the Mcintosh Audio Copensator was an early version of the modern graphic equalizer.

Also from the looks of the inside of the Audio Compensator I would have to guess that the unit was made in the late 1950s early 1960s as it has a hybrid chassis (part tube part solid state) which was what some of the companies did just shortly before going over to all solid state which happened by the mid to late 1960s.
So more than likely from the looks of it, the Audio Compensator may not need to be recapped, as most hybrid electronic technology utilized mostly ceramic caps with exception for maybe one or two early metal film capacitors and the electrolytic caps.

Good luck with this thing.
 
Great score. To post full size pics in your post, click on the attachment and it will open in another tab. Then copy the tab's URL, navigate back to your post reply (or edit the post), find the yellow rectangular box for images, and paste the image URL in the pop-up box, it will then post as [/img] on both ends.

The Image should then appear in your post:

I ran into a system like this a few years ago, had to remove a 12ft console cabinet for the older lady who had no way to move it to the curb (it weighed 500lbs) and got all the equipment for free for moving it. Ended up with a Fisher SA-1000, Dynaco PAT preamp, Sony RTR, Tandberg cassette deck and a very ugly Dual TT

Nice score :thmbsp:
 
Hm, anyone else notice the schematic for that amp? I've never seen plates on the output tubes connected to the opposite winding as the screens before or fed back to be the plate supply on the voltage amp tubes upstream like that.

That's one unique feature of the McIntosh unity coupled amp, a circuit I do not fully understand.

That speaker looks a whole lot like the Jensen speaker on my EH Scott 800B console. Mine doesn't mount the output transformer transformer to the speaker, but its got the same coaxial tweeter type design with the big plastic bucket over the magnet on the back. The crossover components for mine live under the bucket though, not on the side next to the transformer.
 
I don't understand why there is an output transformer on the speaker, the Mac has standard standard output impedances.
 
Perhaps its actually a choke as part of the crossover?


Is this one actually a field coil speaker, or is it a PM jobber? The one in my Scott is an AlNiCo, but its not impossible that they made a similar looking one as an electrodynamic type.

**edit**
aha, found something. It is a PM type, but its a 600 ohm speaker.

I'd bet you a buck that transformer is an 8 ohm to 600 ohm matching transformer. If the McIntosh doesn't have a 600 ohm output, this is a very poor match for that amp. Probably wouldn't be hard to remove or bypass the transformer to get an 8 ohm speaker out of it though.

Military stuff like my Hammarlund Super Pro 210X had a 600^ out, I have a Hammond 600^/8^ step down xformer for it.
