Help:Hammerlund SP-600
I'm having a hard time resolving a problem on an SP-600,
JX-26 I'm restoring. Hopefully there's someone out there
that can help.
On the 3.45-7.4 MC band (only), received signals are somewhat
distorted. Normally, when tuning in a CW signal with the BFO on,
you'd expect an undistorted tone as you tune. On my radio, it'll
sound more like a growl. Signal strength doesn't seem to matter.
I just finished a complete re-capping of this radio. Anyone need
about 60 leaky black beauty caps??? The problem existed before
I re-capped the radio. I was hoping new caps would solve the problem.
It didn't.
As I mentioned earlier, all other bands are fine. Sensitivity and
selectivity is good.
I have removed the ceramic tuning sections, and didn't find any
cold solder joints or flakey contacts. All tubes have been tested
and are OK. Power supply voltages are normal.
