Nice job there are some paper caps in the pre amp section and more 12ax7''s

For the white platter try magic eraser

The Cobramatic kit offered by Gary at VM with the tetrad cartridge sounds really good on these 3 channels.

The SK28 and SK30 have 5 speakers with the same electronics. The 15" woofer is Jensen special design vs Golden voice.

Congrats, nice find. I've got a 28 and a model 30

C10sean. I hate to tell you this but your Motorola was manufactured in 1960. The inked numbers that are on the tuner, the "8M60", the "60" is the year it was built. Having said that, and from what I have seen with the back off, it looks very similar to my Motorola SK-52W which i...

Anything with the 6BM8 amp is model year 1961

Wouldn't you guys want him to get as much as possible so all your unrestored stuff is theoretically worth more?

Blonde is a Westinghouse mono 6L6

Nice find! I'm noticing the vents on the outer edges of each woofer's mounting board, and the 4 patched-over holes on the bottom of the cabinet. I wonder if all those openings are the result of factory experimentation with bass response? Thanks, the 4 holes on the bottom are for the legs when it sh...

Thanks, got a lot of keepers in the basement

SK22 (budget model) with BSR UA-8 changer.

Essentially the same setup as the 93-series Magnavox chassis. Motorola was wise to continue with the 12AX7 audio tubes rather than the 6EU7's Magnavox used. The iron they used in output transformers looks larger than Magnavox. Good luck with the changer restoration. That looks like a keeper... ;) ;...

Believe symphonic made it

The rest of drawings are in the downloads section

October 1958

Motorola was really the king of the console

Friend helped me track this down. One of the good ones. 2 channel stereo from 1959. Sounds fantastic after the recap recap only the phono restoration remains

What do they sound like? Chris Campbell I don't like to power them up on the original electrolytics. While going through the mono amp a bad audio transformer was discovered. A donor replacement 6L6GC transformer from a Bogen DB-15 mono block is going in the little symphonic amp. A member here Who l...

mono push pull 6L6

Made in New Jersey

Late 50's mono and poor man's 3 channel

Did he recommend a retrofit? I have done several and they all worked out just fine. :D Gary offers a Cobramatic kit with a great sounding tetrad ceramic cartridge, requires soldering and glue but sounds fantastic. By now Any NOS astatic cartridges likely sound out of tolerance even with zero miles ...
