a13/L7 step 5 in the alignment setup.

Ok I found it that’s next to the 41.25 trap that was open is this what your saying to adjust the trap or A13

[Yamamaya42]

location can be found on page 6 of SAMS, and shown on schematic page 3 after video det right below C32.

Yes I know which one it is A13 I know where it is and as for the trap next to A13 that was open I put the knob pretty much where is was befor. But for now I was using wood Allen keys which are no good they strip and don’t work I’m waiting for nylon ones to come in the mail.

As for the thermistor I’m putting a permanent jumper in because the voltage was to low for to long when turned on and the pilot tuner lamp was very dim and the thermistor was new.my other Motorola I had was jumped as well and was fine.

you may want to think about getting this as a replacement.

same thermistor used in the CTC-11, same location, should work the same way.

[timmy]

The voltage dropped so far I don’t even trust these thermistors because the voltage drops so bad the horizontal oscillator won’t run so my other moto had the thermistor jumped and I since put new nte diodes in 1 kv 2 amp

thermistors do wear out over time, it's inevitable since they take such a beating, but the exact replacement is hard to find :/

EDIT

here is an NOS RCA version of the exact part in your set.

I already put the exact replacement in it’s new and I got it from moyers it should have lasted longer then this it’s already bad and never got to set down in front of the set to watch howdy doody.

Unrelated on a pilot tv37 there was b+ problems not being up to normal is there one diode or 2 used under the 25z6 3-4 5-8 ok so I didn’t have the schematic in front of me it’s only one diode.

I've got one they're cute little sets. They're sort of the stereotypical radio collector's one TV in the collection/one of the models that if you ask TV collectors that claim to have 40s sets to raios their hand if they have a TV-37 just about everyone will.

[timmy]

It’s to bad I don’t have the 3kp4 crt have to be happy with the green p1.

[Yamamaya42]

I would be happy with any type of Electrostatic deflection type TV to play with, however, the pilot TV 37 is a bit small, it does not stop some putz from asking $1000 for one on greed bay.

[timmy]

I have 7 Motorola 7 inch electrostatic sets but yes they ask to much for the pilot.
