Philco Roundie on going repair
 

Hello everybody, new here to the forum, I am currently trying to restore a 1965 Color Philco roundie model # P5450WA , Chassis # 16M91 , Picture Tube # 21FBP22 , Fly 277. The Flyback in the set is bad, Does anybody know where I can purchase a good replacement. I herd that one made by Thordarson is good. Also need information where I can get Capacitors to replace paper capacitors.

thanks,
Bruce

Welcome! Nice looking Philco!

Go to moyerelectronics.com. Get their email address & write them with your needs, they will reply very soon letting you know what they have. Many of us on the TV forums have bought from them & are very happy. Yes, I think in general the Thordarson flybacks are the best replacements.

Good places to find caps are radiodaze.com or justradios.com. There are a number of others. Not sure if Moyers carries the caps you need? Shouldn't be too many paper caps in that beast, I wouldn't think.

Is there a safety glass on that kine? Seems awfully light for some reason to me...

Havent seen a Philco set in 25 years. We used to have alot of them come thru our shops with fried flybacks. I do remember that much.

www.justradios.com is where we buy most of our caps. We go through a lot of caps and have found their caps to be of good quality and price.

Most of the caps in tv sets of this age I have seen are mylar or ceramic and still OK. If it has a maroon or orange case and leads coming from the bottom it is most likely mylar...have seen bad electrolytics in this age of set though.

Thanks for info everybody, the picture tube in the set is not the original tube, it was replaced in the 1970's with one that did not require a safety glass, I think not sure

Hey Bruce,

Nice Philco roundie. I believe your model 16M91 is a 1966 set. I'm a little confused. Did your Philco originally have a 21FBP22 picture tube? Or does it now have a later tube? Also the 21FB did not have a bonded faceplate and required a safety glass. Your posted picture looks to have an unbonded picture tube.

The original would of been a 21FJP22. I think.

In the 70's there were rebuilders removing the bonded face and putting a metal band around the outer edge of the tube, this supposedly would prevent the glass from going everywhere in the event of breakage.
I never tested this theory.

So how was that supposed to work? If the face became shattered, then the band would then pull in on the weak outer 'side' of the tube and sort of collapse it in too, instead of just the tube's face going in by itself and bouncing right off the back and into one's face? More of a complete implosion than just the front screen. Sounds logical I guess but boy can you imagine having one of these sets and you see your 3-year-old rapping on the screen with one of his toy hammers?! Yikes!
I could believe it working more if the circumference was also wrapped in plastic taping or something so it would hold together like the cemented faceplates did. Otherwise it's still just glass shards everywhere, just more of them.

Welcome to the board!

On more-modern square(ish) CRTs from the 70s on, the rimband certainly seems to work if you're belting a breezeblock or hammer through the screen (mis-spent youth speaking here!) - all the glass'd stay inside the case of the TV, and the shattered remains of the shadowmask/rimband'd be in the case too:

OK, so it's a b&w portable, and the glass is MORE intact than on the 25inch colour tellies we bust at school, but you get the idea. My nefarious mate Rob did that portable, and here he is again with my old monitor:

Obviously the implosion protection isn't infallible:

Not big, not clever, but THAT breaking glass really IS an interesting sound... At least all the tellies that died at our hands were junker/broken modern plastic POSs...

I think the term "bonk bonk bonk BONNNNGGGGGSKLAASSSSH!" would ring a bell. Not funny!

Consider installing safety Glass
 

Check CRT and verify if safety glass should be installed. I would not trust only a metal band as safety device for an older CRT. The risk is too great not to have Safet Glass!!!!!

:sigh:

I have 2 sets using 21FBP22's and they have a safety glass that is attached around the edge of the tube so the resulting installation looks somewhat like a 21FJP22 but there is no bonding to the tube face. One of the safety glasses is etched like on a 21FPB22 and one is clear.

I know the difference in the look from the plain 21FBP22 with no glass as my CTC-10 has a 21GVP or 21GUP22 that has no attached saftety glass but it has the seperate rectangular tempered glass panel.

just looked at the tube it does have metal band

I need more help if anybody out there can help me, Just got a repy back from moyerelectronics.com about a FLY 277 and it was "I am sorry to say none of are stores have any left. good luck on your search. "

Im tempted to try a flyback off of a GE chassis, but i don't want to do that

hope someone can help
