Scored an Admiral 19A11

Dittos to jr_tech on leaving the caps alone unless one is leaky/shorted. Their values are for bandpass-shaping so are fairly critical.

I checked the voltages on V1 and V2 with the tubes removed.

Well Late this afternoon I decided to replace the mica caps in A4. I thought that while I had it out, why take the chance. I replaced them with 500V 5% micas. I had the 10pf but didn't have the 130pf so I put 2 in parallel. When I checked them with my cap checker I got 129pf. Good enough. And I also changed out the 15K resistor which read 23K once removed. BTW, all the caps in the tuner were replaced using carbon film caps.



I re-installed the tuner and I now have a much better picture.



On to the alignment.

Excellent! did the plate voltage on the 2 6J6 plates change?

I haven't checked it. I'll do that and report back.

[Crist Rigott]

Yeah, I have 137V at pins 1 and 2 of V2 the 6J6.

Oops! Made a recapping error! Before I do an alignment I take small pieces of masking tape and ID the places I need to hook to during the alignment. In the Sams these consist of letters A thru F. All went well till finding test point F. Test point F is at the junction of R22, R20, and C13. When examining that spot I noticed that C13 wasn't at the junction! It was at the "bottom" of R20. I checked my notes and sure enough I soldered C13 to the wrong terminal. I soldered it to terminal 3 (counting L to R) instead of 4. I easily moved it to the right spot and labeled test pont F. I never would have caught that if I wasn't pre-labeling those test points. Excuse me while I go buy a couple of Lottery tickets!

The picture is getting better by just watching TV. Star Trek to be exact.
