 I have an Alpha 78 that wouldn't turn on and I found that a 10K power resistor 
that dropped the 220 down to 110 to turn on the main relay was open.  When I 
replaced it, the amp came on but when the off button is pushed, it only turns 
off momentarily while the off switch is held.  When I let up on the Off switch, 
the amp comes back on.  Any ideas?
