Title: Knight Model 93 SZ 682
Post by: DummyLoad on December 09, 2008, 08:39:50 pm

i got my paws on one... in pretty nice shape overall, once the 40+ years of dust was removed it looks fairly nice. gonna fire it up after a cap job and install grounded pwr cord. we'll see what it can do as-is... :)

3 x 6SC7, 2 x 6L6-G, 1 x 5U4-G    looks like 30 watts output... i'm guessing OT primary Z is 6k6. 

i'll post pics shortly.

I know this was forever-ago, but how did it turn out? I've got a buddy hauling one back from the east coast he wants me to look at.

Very nice tone! - Grafted in an Ampeg-like preamp/paraphase phase splitter.

Here I was thinking "Cool. A bunch of sound samples!", only to realize what you've given me is SO MUCH cooler! Thanks, Pete!
