I found a nice Admiral on that auction site, got it a few days ago. It was playing VERY weakly, but is in great condition. Looks almost new except for a couple scuffs an a tiny scratch on the metal faceplate. I opened it up, noted a small elytic on the edge of the board. I jumpered it with a 10 mfd unit and BOOM, the radio came to life, playing loudly and picking up both the local broadcasters clearly. It needs the volume control cleaned but otherwise is ready to go.
Of course it is MADE in the USA, my specialty.

My brother bought one of these way back when,
& they are very good units.

His was black in color. He paid $30 or $35 IIRC.

Admiral as I recall, were a bit late getting to the transistor radio party. The ones I hav experience with were all well made and performed well. This one is no exception, nicely built and , once I changed the bad electrolytic plays great, real loud for such a small set. The tuning mechanism is interesting, it has the metal friction-wheel reduction drive often seen on large tube sets. I have never seen that style on a transistor set, very unique. And the winding pattern on the loop stick is also unusual, it's like many of the crystal set loopstick, jumble wound to reduce interwinding capacity. Very neat looking too. It seems to work because the set is sensitive and picks up lots of stations.

Neat radio Bob and glad it was an easy fix !

Have seen exterior pics of these on Ebay, but didn't realize how deep they were and what they looked like inside---I like it !

Have a few early Admirals myself and they are good performers...

Thanks for the pics of yours---especially the interior.

John

Congrats, that was a good pick up, because they aren't that common. I too have one, but have to say it's performance is mediocre, which is surprising for the brand. Glad to hear that your's works well though!

The Super 7 is really a thick radio, kind of surprised me when I got it. I suppose they had to make room for the magnet structure on the speaker, and the air variable tuning capacitor.
This one seems to have had very little use as there are only a few mars on the cabinet, and no wear on the control knobs. I added the closeup of the tuning mechanism, very interesting for a portable.

Well, the photo didn't load ? Don't know why.

Hey Bob,

Neat that your Admiral has reduction tuning---sure makes a difference with a good performer ! You could edit your post and try attaching the picture again...

My Arvin 62R49 also uses that friction-wheel drive---see picture below... Was amazed when I first saw it as it does seem to be a rare mechanism in a transistor radio !

Don't you just love it when they mount an electrolytic capacitor right at the edge of the circuit board.

I was able to change the one bad electrolytic cap without even moving the circuit board. It is visible next to the earphone jack. I constructed the cap using a modern unit and made it look vintage, preserving the visual appeal of the set.

I was able to load the photo of the tuning mechanism too.

I find it interesting there is one transistor that is mounted in a socket. I think it is the converter transistor, not even sure it came that way from the factory. Anybody else have this set with the same arangment?

Yuppers, here's mine, so I guess we can assume it's by factory design.

Have a horizontal Admiral which also sockets only the converter transistor---don't recall the model at the moment, but it's of the same vintage...

Wow, cool radio! Dig those square ceramics.

John, thanks for the photo of yours. So the socket is factory, cool. They must have had trouble getting the sets playing and opted to provide sockets to make change out easier. Not unusual in the early sets. First generation Zenith, Emerson, Magnavox and RCA all transistors were socketed as I recall.

John already gets too much credit on the board... :wink:

I answer to Richard... :D

Credit goes to those who deserve it, mostly.
I guess it is isn't a competition to see who gets the most credit, rather, a tribute to those who are so generous in helping others who lack knowledge or ability to diagnose and repair these wonderful things we collect and preserve, or as I like to say, save from the landfill.

I simply thought that you were referring to the pic I posted above, when thanking John. Yes, he's deserving of credit for all he contributes, no argument; I was just jivin'.

Richard,

So sorry, I got confused. Yes , I was thanking you for the photo of the other Admiral Super 7.
That's one thing I love about this forum, people willing to step up, and post photos, give hints and repair ideas about the hobby. There is so much knowledge out there that is the accumulation of decades of tinkering and collecting. As we lose members to illness or old age that pool of knowledge is becoming smaller. There have been many brilliant individuals whose contributions to electronics and all its variations that have gone away. It is sad to see.
Thanks again for any and all help and all the comments to everyone. I remain in your debt.

Bob.
