[Swan] 700CX

[David Shipley]

I found the cause of the HUM! AFTER I replaced ALL the caps and diodes in 
the power supply. It's a bad ground connection in the power connector in the 
radio! I can put a jumper between the chassis' and it works! I guess I 
should try to remove the cover from the can the connector is in and fix it? 
It looks like it's only tacked on with solder!
When I leave the rig on for about 5 minutes the audio goes way down! I've 
checked the tubes. They seem good except for the 6EW6. Any suggestions about 
that?
