[Boatanchors] Need Microphone Information

Thu May 19 15:46:50 EDT 2011

This SBE-33 was my only rig from 1965 to about 1969.  I used it at home 
and took it and a Johnson match box on several vacations including a 
couple of trips to St. Croix.  Then it sat in the closet for a number of 
years until I resurrected it a couple of years ago.  I had to go through 
and replace all the paper and electrolytic capacitors.  It has two 
problems.  The VFO drifts but what 1960's SSB rig didn't and I have to 
advance the audio gain as the rigs heats up.  I may try putting a muffin 
fan on top of it to pull air through.  A little more cooling might help 
both problems.

Brian, I started aligning the HA-2 and my power supply decided to go up 
in smoke.  The one of the two seriesed 40 uF 500V HV capacitors decided 
to give up, smoke and black goo running out of the bottom.  My fault for 
never replacing them.
