[R-390] T-503 Top - slug cracked

[Jim Sorenson]

Gentlemen,

My Stewart Warner 390A plays reasonably well and I've run into no major
problems using Chuck's suggested alignment procedures until ----

Peaking of T501 (top and bottom) ok at 467
Peaking of T502 (top and bottom) ok at 443
Peaking of T503 (top) peaks at 455 with T503 (bottom) cracked and stuck in
the coil form.
I've assumed that the bottom (good one) is L512 and the top one (stuck) is
L513)?

I'm peaking off of diode load which comes right off of L513 (detector)
through fixed L502.

Obviously I'm going to have to replace T503 or break down the slug, fish it
out and replace it, if possible.

This IF unit is a Capehart - everything else is Stewart Warner.

Can anyone tell me how I might test if the present combination of L512 and
L513 are ballpark having not been able to interactively walk both up to a
joint peak on diode load at 455, or am I nitpicking? I've been through an
entire alignment at least once and the unit sound fine to me?

Where might I find a replacement for T503? Could I replace with a generic
455 Kc transformer? I'm not planning to sell it or do a full restoration on
it -- just use it on 160 CW and run the IF out to 455 Kc. SDR converter
which works fine with the unit.

Since I don't really care about AM audio fidelity, might it be better to
align T501, T502 and T503 all at 455 Kc and not stagger them?

Any thoughts on this would be much appreciated.. I've looked through the
archives, but could not find anything pertinent - If there is something in
the archives that might help, I'd be grateful if you could point me to it.

Many thanks,

Jim
