Admiral 17T1: Never Give Up, Never Surrender

[Winky Dink]

While rethinking what I've done with this set I need to deal with one issue at a time. First issue is the wiring of R41, replacement of C37 and C39, and the destruction of the H-size pot. Everything I've said is based on assumption and memory (or misassumption and forgetfulness) from 10 years ago.

I'm going to post here several 17T1 and 19A1 schematics. I'll follow that up with photos showing what I really know about these components. Patience, please...I have to write everything offline first because of my slowness I can't even write a quick response without being logged off.

This is overlay of the Rider 19A1 schematic (Red) and the Telaides 12T1 (Black):

Regarding my scenario of destruction of the H-size pot after replacing C37 C39 with 630 volt film caps. The problem with the image on the CRT may have preceded that blunder, and instead of one or both of the 630V caps failing, I could have miswired them

Have you done voltage checks around horizontal, vertical and sync tubes? It would be interesting to compare to the values posted in the Telaides info.

Is there confusion caused by v12 being labeled as v13 in the Sams info and/or missing power supply connections lost in the fold of the Sams page?

Winky Dink, please chose a schematic and stick with it. You can't mix and match sections from different schematics.
Also you are just confusing every one shifting back and forth, the part names (like R41) are different between schematics.

If you don't have the correct parts needed you will have to get them.
