Admiral 19A1-S-A troubles

[Kamakiri]

I've been through hell and back on that chassis

Horizontal sweep transformer is suspect. Sams says 50 ohms primary, 150 ohms secondary. It shows the same part number is used for both horizontal and vertical transformers, which makes things easy to compare.

EDIT: Be very careful when moving the leads around on these transformers. They tend to be brittle, and can go open if you look at them the wrong way.

You would not by chance mean the Horizontal blocking transformer T4 (the one that looks like a large I.F. can located next to the horizontal oscillator tube (v-12b 6SN7).

i did notice that i am getting some wrong voltages on a couple of the pins on that section of the horizontal osc tube. however, all i have got to work with is the ryders schematic that i downloaded from the E.T.F site & there are some descrepancies with that schematic & this particular admiral model.

if it turns out that the problem is that transformer, where can i find one.

Nope, I believe it's T2, at least in the Sams. Here's what mine looked like with a bad T2. Look familiar?

If you have the chassis sitting on its side with the underneath facing you, and the picture tube facing left, the transformer will be just below the chassis cutout for the picture tube, on the left side of center down low.

I hate Riders anything, but that's me

Try this.
