Admiral P-1110-A

Post by Wildcat445 on Fri Sep 18, 2015 6:05 pm

I have one of these little sets. So ugly, it's cute. It has ten tubes, several of which are Compactrons, and an 11CP4 CRT. I'm not sure whether this is referred to as a 10" or an 11" set. Black & white, of course. Chassis C21A1 (I think). The CRT lights with snow and sound. It appears to have decent vertical and horizontal deflection as it lights the entire tube, no black lines at the top or bottom of the CRT. I don't have anything else at the shop to feed a signal to it to get a good picture. It has a thirteen channel tuner, and no UHF. The tubes are coded "3226422", which means Tung-Sol supplied during week 22 of 1964. The high voltage cage does not have a tube rectifier, and it appears the flyback may be in a metal compartment. I'm not sure what is going on there, certainly different from anything I have seen previously (?) It appears to me that the CRT is put in upside down, as the anode plug is on the left lower side of the CRT, where I typically see them on the right hand upper side. Maybe the CRT is mounted differently in order to cram everything into that small space. It has a black plastic cabinet. A PCB chassis that appears to all come out in one piece with the tuner. I'm not really sure how to get the chassis out in order to replace a handful of capacitors. Some of the capacitors are 1000 volt and have "2% maximum drift" written on them. I consider myself a novice at TV repair. A TOTAL novice. I'm competent to remove dust and I can test tubes. Otherwise, I'm starting from scratch. For three bucks I can afford to experiment with this TV in hopes of gaining enough experience and confidence to do one more worthy of my time and attention. My wife thinks this little set is cute and does not want me to "hack it all up just because." This may be my project for next spring. I'm up for education. I hope some kind soul out there in cyber space will be disposed to lend me a hand. If anyone reading this wonders whether I know what I'm doing, the answer to that would be "no".

I've got some pictures, and will post those as soon as I get them processed.

Sounds like that one ought to have some tolerance level to it. Good choice.

Admiral seems to get high marks for being easy to service, relatively speaking, and good performers when they are restored. I'd bet money that this little TV would do pretty well connected to cable. I don't think it will work with satellite. I believe it would work just fine if I did nothing to it, but the purpose of my getting it was to learn something. It looks to me like the entire "chassis" or the workings of the set are mounted to a metal frame. If I were to remove three screws and also remove the knobs, it looks like to me that the entire thing would come out of the cabinet after the CRT was disconnected. The part about that which might present a challenge is that the deflection yoke might have to come off the neck of the CRT to get everything apart. That parts needs to be put back on properly. I need to read up on "Yoke 101" to better understand the process. I'll bet real TV guys are getting a good laugh about now.......

Here are some pictures of this little TV set.

It is so ugly, it's cute.  Could this be a member of the "Playmate" family of Admiral TV's ?

This one has a boat load of plastic capacitors that look really hard to get to.





Tubes were supplied by Tung-Sol (322), in 1964.  This set is VHF-only.





I have not actually watched anything on this TV yet.  I'm happy to hear that they are good performers.  All the tubes appear to be the originals with the exception of the 17JZ8 vertical amplifier.

When you get ready to replace them, try the solder sucker mod I describe in thr tips section.

That's a good idea. I need to figure out how to get the chassis out far enough to change the caps. Methinks that the yoke will need to come off or be slid back to get enough room to work. Scary stuff at this point. I am entering new territory here.

I would give that a good deal of study before taking it apart. I'm sure it has some secrets as to it's access to be revealed.

That is exactly what I am doing. There has to be a logical order to that thing.

Always remember, someone had to build it, and someone had to repair it. Very Happy

Those white porcelain capacitors are paper, and, no good.
If you see orange drops that are turning brown, they are no good. The set is best completely removed from the cabinet. Be careful of that picture tube. Highly fragile.

Thanks, Bill. I figured I would have to remove everything to do those caps. I think I can leave the CRT in the cabinet, but the guts would all have to come out. It appears to be mounted on a metal frame in a big chunk. The yoke will have to be slid off the CRT neck to get the chassis back far enough to replace all the white capacitors.

I still recommend removing chassis, tuners, and, yoke completely. Leave picture tube, and, speaker in cabinet Further, it will need new electrolytics.

Got it. That looks reasonable. Would you be good enough to instruct me in "Yoke 101" when I go back on with the yoke? The electrolytics are in a can on the right hand upper corner of the chassis, not visible in my pictures. It will be accessible with no problem once the chassis is removed. Thanks, Bill.

Just be safe WC I worked on TVs at a manufacture coming off the assembly line. I will never work on any again! It was easy there as you worked on the same B/W chassis, I probably fixed 1000 or more when I worked there for a year while in college. They have some really nasty HV and it hurts! I never totally understanding the workings of them but most of the time I could look at it and know which crappy part was, well crappy. Miss wiring took a little longer! Amazing how someone as dumb as me, with a lot of exposure on a given chassis could repair a chassis in less than 5 minutes.
Just watch out for the nasty HV.

It would be wise to make sure all devices capable of retaining a charge are discharged prior to performing the repair/restoration.  I'm sure you already knew this.  Here is a little page with some guidelines on doing so, so there are no surprises.
