Hello........

During the last contest I began to develop a problem. When I key the alpha, non 
qsk mode, everything is fine. When I let up on the key the amp continues to 
mute the receiver. If I tap on the left side of the amp, the receiver comes 
back to life. Looking at the schematic, it appears that K-10 (dpdt/24vdc) relay 
is sticking or k-11, 24 vdc reed relay is sticking. I suspect the former.

Knowing Alpha, K-10 is a specially designed relay. Any thoughts before I have 
to call them?


Also....does anyone know exactly what type of fuses the Alpha 76PA and Alpha78 
use? The manual omits this info. I seem to recall something like MDA-20 amp 
ones.
