Yes, it played through his speakers
When you receive it, post pics of the top and underneath. The eagle eyes here can tell if it's really been properly restored.

Looks nice...How does it sound with your favorite music sources, discs + LPs ?
Very thorough job! Some boutique caps, damping on the small electrolytics, new output tubes. I'd say you got a nice deal!
Haven't had the guts to run it yet. But after everyone's input, I will swap it into the system this weekend.
what components are doing the damping?
He's got some 3M adhesive damping material on the small electrolytics underneath. It's an audiophile thing, might make a difference in the sound, might not, but it doesn't do any harm. It looks like a very personal restoration with preferred components. Maybe he did it for himself then decided to sell it. I don't think you need to worry about using it.
It looks good to me, Just no volume make sure you have 8 ohm speakers wired in and run it add some volume you can tell more about how it sounds !!! you can go to "Made in Rochester" you will see many Stromberg Carlson amps, consoles, turntables, tape machines. first once you get to Stromberg Carlson download 1961 DJVU HIGH RES to read and open all the files and click to download which one you want to download then just double click the file on your computer and you can see all the info on each amp...

^ Hey you'sa beat me to it...
My take on the foam or other stick-on is that there's very little clearance between the chassis and bottom cover - a little extra padding is a good thing. As for resistors, I haven't seen one of these yet that didn't have some resistors wildly out of tolerance. You gotta check 'm all and if you're unsoldering to replace a cap, might as well do the resistor at that junction as well. If the "pop" on power-off bothers you, the fix is to add a .047 or 0.1 uF across-the-line type cap (X-cap) across the terminals of the "switched" outlet on the back.
Since my site was mentioned, see the link below
