Admiral P17E31 scored
 

Thanks to WISCOJIM I made a nice little haul today including a 1958 Admiral P17E31 portable. It has a metal cabinet with gray hammertone finish. Seems to be in good shape - just a little dirty.
Not the type of set I usually go for, but it was free and is slowly growing on me :yes:

I also picked up a partial Riders set. I think volumes 3-28 were there, but I only took some - just don't have the room for everything.

Maybe the schematic for this set is in one of them ?

Also got a couple video cameras and a bunch of random tubes.

Nice haul!

DANG!!! I just tossed out the monitor that sits atop that sony camera... and i know it worked... Had it sittin here for years...

Wish this score was a few weeks sooner..

SR

Oh well. Do you think the camera will work with a B&W TV ?

It sure will. i had one back in the 80s and i used it on a tv. it will require a LINE IN to feed the video from it.. it should operate at 12 volts..

I found this set in one of the Riders (#24) I just hauled home :)

I can't believe it doesn't have a transformer. It must weight 50+ lbs!

I popped the back off this set and took a look inside. It appears to be in pretty good shape - nothing obviously blown.

Horizontal output tube looks dead.

This could be why :tears: I see a few cracks in the old coating so I suspect this was a attempt to stop arcing.
I haven't tested it yet. Hopefully, it's still good under all that tape.

Now to test the CRT. I would have used my Sencore CR70, but I'm missing the #4 adapter :(
So I had to drag out my old B&K 440. The emissions came right up into the good range. The life test stinks though - even after an hour of running. Oh well, I'm sure it's good enough to produce a picture.

I had one of those set about 20yrs ago. Good playing little set. A little cramped to work on.
Terry

Any suggestions for taking it apart ? I've never worked on a portable like this.

Bob,

You can use the universal adapter with the Sencore CR70 if you are missing the #4. Unfortunately, most of what I test has to use the universal. Really!!

Kewl set !

If the chassis looked like that before any cleaning or blowing out, and with the number of stock tubes that I see, I would say that the set has low hours on it! Is the CRT an Admiral?

The chassis on these portables usually unbolt then tip and remove out the back, unplugging the anode can be a challenge sometimes.

I never pay attention to the life test, if the tube goes up to good with little warm up then it's fine.

The Fly looks a little worrisome though, shouldn't be too hard to find one though.

When i rebuilt my motorolla i actually removed the CRT first with the yoke connected. It had a plug...
then removed the anode to the CRT.. It made removing the chassis alot easier...

SR

Thanks for all the tips!

OK, I thought that would be the case. I guess it's just a matter of figuring out which CRT pins are filament, grid and cathode.

That's what I was thinking too. Other than the flyback, it's very clean inside. Yes, it's an Admiral CRT and very likely the original.


BTW I finished sorting through all those loose tubes. No hidden treasures, but I did find a bunch of good 5U4s and 6SN7s.
