[AMPS] Mods to TL922A

[Ben]

I have a 922A amp, the tubes are in good shape
but its a dog. I've heard there are several Mods
around that can lift it off its knees, like...
	1. Change biasing during key down
	2. Adding cut-off bias circuit during key-up
	3. Adding QSK using RF sampling
	4. Any others
I've searched the net and have only just got on the 
reflector. Before spending the time designing some-
thing, I was wondering if some kind soul could supply
the information or show me where I may find it
Thanks in advance
Ben     3 to go
