I found the bad tant cap, it was a 22 ufd, 20 volt, not any AVX but a
yellowish tan blob with a big L. I replaced it with an electrolytic. I
found it using my Fluke 87 that measures to the nearest tenth of an ohm and
only the suspect cap would flicker between 0.3 and 0.2 ohms, all the rest
were 0.4 or 0.3. Now I'm kicking myself for not buying an HP meter that
could read 1/100ths maybe 1/1000ths because I could see no use for it. Now
I can see a use and one is on my list but nevertheless my Fluke saved a lot
of desoldering. The Wavetek still doesn't work as something else is
keeping the voltage low and I think it might be a regulator. Now I wish I
could find a schematic for the Wavetek 188-S-1257, as it would keep me from
wasting so much time.
Thanks for all the tips. guys.

Sometime ago I think I recall someone posted or wrote an article on a neat
way to isolate a shorted component on a pcb using common test eqpt but I
can't recall the methodology. I'm trying to find a shorted component on
a
Wavetek 188-S-1257 signal generator. The B+ line reads about 0.4 ohms and
I'm not having much luck disconnecting componets. I don't have a
schematic
and my eyes ain't what they used to be for tracing and I want to minimize
the unsoldering. Does anyone recall the article or have a good way?
tnx
