Predicta... Gonna go check if out

[DaveWM]

17DRP4 has the low volt filament. If rebuilt could be higher and pin out could be different.

On the schematic there is a tap on the power transformer for the CRT, so yes it does have the lower filament voltage. The CRT is also the same part number.

Bone like my admiral TV.

Nope, sorry, no reproduction knobs are made Several NOS replacement contrast and volume knobs were on ebay recently so they are out there.

Looks like there's a few places online where I can get a generic concentric knob sets with set screws, which will have to do until the real thing appears. The thought crossed my mind to steal the antenna from my Admiral... maybe I better not do that

I looked at my master list of repaired sets from my service days. It's on a floppy disc that runs on an Apple IIe.

I repaired 12 Predicta's, and only one had a power transformer.

I used to have a box of knobs, but they are long gone, now.

Mine has seen a few repairs... the few tubes I pulled were all different brands.. Westinghouse, Sylvania, etc. I can't wait to get it apart and look at it in detail.
