Oh yeah, this one has the 50 cycle transformer for Canada, you can barely see it but it goes almost to the top of the cabinet.
Bet it weighs at least 20 lbs more than the American version.

A good deal for someone in Toronto. That's typically what they go for when sold in venues other than eBay.

Ok, why did this get moved to "online Auctions and Sales Forum"??/? :?

I think it may have been moved by accident since some of the discussion included links to auction and sales venues. I moved it back to the TV section since the main subject is about the TV you bought locally.

Thanks Dave!

I didn't mean to sound so critical. I was just surprised to see it moved.

I'll have to see if my Sencore CR-70 has setup info for the 7JPx CRT's. It won't have the socket, but it is provided with a set of clip-leads for just such a test.

It will be quite a change considering all the TV's I've ever worked on were magnetic deflection.
Clearly electrostatic is a simpler system. Too bad it doesn't work for large high def angle CRTs.

Some CR70 manuals have the 7JP4 data, others don't. Here 'tis, just in case.

Several 7jp4's have sold for $125 and up the last few weeks in unknown working condition!!
I would be glad to take that set off of your hands if you want to sell it. :wink:

I'm happy to say that I just checked the CRT with my CR70 and it tests strong. Holds in there on life test too!

I'm not sure I will sell it, but I will consider it. Just such a cute little TV.

Steve,

You gotta keep it. It is so cute and you have a good 7JP4. That puts you in the lead!

Thanks Don, I think I will keep it.

Though, I am a little worried. There is so much good about this little TV, that I am wondering why it was taken out of service?
Looking at the chassis, it is very clean. each and EVERY tube is Admiral labeled, which amazes me. It is clear the TV had plenty of use. Many tubes such as 6SN7 or 6SL7 have silvering on the glass above the heaters, indicating heavy use.
Under the chassis looks very nice and original. There is no indication that it has ever been serviced.

The term "Too Good to be True" comes to mind?

Oh, look at that nice turret tuner!

That set has a lot going for it. It has a power transformer, it has a turret tuner, the CRT is good, not too cramped under the chassis and really, the parts are not exotic. Most likely it was taken out of service because of failed capacitors. I would bet that the reason it was taken out of service was because the 6KV capacitors are bad. You can get them easily from Just Radios or Allied and they are about $3 each.

As for the silvering above the filaments in the 6SN7 tubes, that is not unusual for them to do that. They can also still be good and have that silvering. Did you test any tubes?

There's a good possibility it had nothing wrong with it when it was taken out of service, it could just be they got a bigger set and lost interest watching a 7" set so in to the closet it went for the next 50 years.
Of course sitting for that long will ruin a capacitor even more then using it will so you can figure they need replaced, especially the 6KV ones.

The only thing to worry about as far as finding a replacement for is the 7JP4, they are getting expensive these days.

I see at least three indications that it has been serviced, those black capacitors with yellow writing are not original to the set. That was likely done in the mid-1950's when that style of capacitor was popular.

I agree that if you recap this set it should work very well, start with the 6KV caps and proceed from there. You will likely at least get a picture after replacing those.

After you watch it for a while when everything is done, you will understand why they eventually stopped using it. They are cute little sets and display a very watchable picture, but compared to even a 10" set leave a lot to be desired. By the mid-late 50's nearly everyone who owned a 7" set would have upgraded to something with a larger screen.

Dennis, your right.
Why didn't I notice that?
I guess I was looking too closely at the electrolytics. :oops:
open mouth insert foot...

I'll be replacing at least the electrolytics and HV caps before powering it up. Its been a while since I worked on an old TV like this.
Don, I've only checked the CRT. need to get to the tubes soon. Much has been going on due to Christmas :wink:

Hey Steve,

Didn't want to "let the cat out of the bag" but what the heck it's Christmas. :)

I like "leftys" TT radios, not many made, this Admiral is the same. Take a 2nd look out there & see how many portable tabletop lefty sets "are out there." 8)

Not many I presume, Admiral might be the only manufacturer who made them, I've never seen another TT "lefty." Definitely worth the effort to restore & when once done, maybe set it on the Strat :shock: & see how she looks. :wink: :)

Though I'm only about a 2 month rookie into TVs. :lol:

Yikes :shock: That's crazy! These are the most common of the Admiral 7" sets. The black bakelite 19A12, "Chinese grille" 17T12 and maple 19A15 are the harder to find ones.

By "lefty" do you mean the screen is on the left side of the set ? That's actually fairly common.

I hope it's a pick up deal, the seller has some pretty poor feedback on shipping vintage electronics!

I have a few 7JP4's. Two of them work well and the rest are weak and have very poor contrast. I used the settings above to test them on my Sencore CR70 and they all test the same, well into the good range. Has anyone else had the same experience?
