Hi Barry, Very good, If you need parts for it I have some Blaupunkt chassis up in the barn. Keep me posted. Ross

Hi Ross,
I'll give that a try.  I disconnected the filter caps and jumpered in
some good ones and I think the voltage did rise just a tad, but not
much.  I don't remember exactly what I was getting before, but I'm now
running about 25V low (214 instead of 240).  I checked the transformer
output and it's good so it must be the selenium rectifier.  I know
they're bad about burning out in a smelly way, but I did not realize
they get "resistive" over time.
Apparently the small rise in voltage really helped the FM.  It is a
lotclearer than it was last night.  It really sounds good now.  I need
to align it, but in the meantime, at least it is working nicely.
Yes, it is the 460kc transformer I disassembled.  See it at:

As a side note, there are two small spring clips that hold the internal
assembly together.  Last night, I was reassembling the first clip and it
went "p-ting!" as it flew across the table, ricocheted off the face of
the signal generator, and then flew across the shop.  I looked for it
for about 1/2 hour last night and gave up.  Today, I pulled almost
everything off the floor on the side of the shop where I last heard a
"tink" and finally found it.  At least the shop got a good cleaning...
Thanks again,
