[Drake] help requested on TR7 losing AC power

[Andy Elliott]

Thanks for the many replies to my request for help!  I am using the PS7 power supply, and I was operating on 10.1 MHz with good SWR when I lost AC power.  
 
I cleaned the two pots on the PS7 (one of which is the current limiting pot) and so far, rig is now running fb.  If this doesn't take care of the problem, I'll try the other suggestions and let the list know what worked.
 
The list is a great resource!  Thanks to all who responded - the extent of your knowledge is awesome.

My TR7 has lost AC power three times today when I began sending CW. Each time I've been able to turn off the TR7 power switch and turn it back on again, and the TR7 comes on OK. I have been able to transmit CW after the last episode. ALC indicator was not on when power was lost. The AC circuit is not overloaded. No linear amplifier in use. Any ideas as to what might be going on?
