Recapped a CTC 7AH..still have a problem

[miniman82]

.6 ohms is bad, mine had like 3 or 4 if I remember right. If you can disassemble the transformer, it might be possible to repair. Sometimes the windings will be shorted near the top, where you can still get to them. If it's the type that's potted in wax or whatever, good luck. I wouldn't want to even think about the mess that would make...

If anyone can cross the numbers I have a transformer #300251-1. If memory serves me correct, I think it came from a RCA upright chassis color.
The lead colors are black, black/white, green, green, beige, beige/green, red/black, red/green, and what looks like orange. If it'll work it's yours the shipping.

Thanks Zenith;
waiting on what,Mr.Bill of Moyers Electronics has to say about the old RCA number crosses too...I'll compare it to what you have..if they gave me sticker shock! I'll need what you have...be so kind in looking @ the Sam's for mine...its in folder 459 or 495... I forgot what - number after that...Its a CTC 7AH Grenoble style with ultrasonic wireless remote!...please pm me with you're phone number let's talk

Zenith'and Phil'
it is a potted tranny on mine..about the size of a small loaf of bread
and heavy...i take it that yours is the same

[47'Plymouth]

Zenith'
please look and see what chassis number you got that from?..according to an original RCA shop manual dated '1957 the early production power trannies had the two 5U4's tube sockets mounted in the top of the transformer case like an old Philco 37-60 radio's tranny..what's listed in
Steve McVoy's website link..mine's is the later version that didn't have that twin Tube rectifier setup in the case,..mine uses 2 "Top-Hat"style diodes on terminal strip..with one solid red on the bottom end of the strip and the Red/Green tracer soldered in between the 2 diode top end with a 0.1uF@ kilo-volt ceramic cap to ground,..both are still tested good is your's like mine

primary - 117v 3.8a
sec 1 --- 150v 0.880a
sec 2 --- 6.3v 2a

remove the caps at the interlock.

[47'Plymouth]

I did..
completely unhooked the tranny from TV set,and still got the same resultsDEAD SHORTin the primary..Mr.Bill @ Moyers electronics called me last night..informed he had a NIB power transformer in the box
for my model 7 AH..sent him a money order off today..and I'll still obtain one as a spare out of Louisana...that should cure the problem will have the original rebuilt later when possible$$

[zenith2134]

Awesome, you found a NIB transformer! Very lucky.

[47'Plymouth]

Yes folks;
from Moyers for the amazing price of $87 bucks! I'm sorry peoples
that was the last one they had...even if its been in they're stock inventory
for the past 45 years on the self

[47'Plymouth]

New one is now mounted and working up the rewire hookup
got one that's the longest wire,.its a white/black tracer.heavy gauge
can't remember where it goes..its over a foot long..i matched up
the rest and one left hanging...haven't powered up it yet..just want make sure
for correct reinstall...can you power up on the bench without any of the
tubes in? to check the voltages are correct after we figure out where that single power lead goes...will it fry anything without all of the tubes not installed??

[enrico6v6]

Uhh what a good crt!!! Beautivul vintage style colours, just like Technicolor... I love these!

[47'Plymouth]

a price of a new car even back then 53 years ago
