Noll:
I don't think I have the HD power supply. My BTI was built in 1966.
Regardless, it looks like my three back-up 3-1000z will never be used. I
picked up 3 spare full output tubes 3 for 300. total.

Ted,
I have a BTI LK-2000HD purchased new in August 1970. With 100 watts drive on
20, output is 1800 watts in to a dummy load. Still have the original tube in
the amp. About 20 years ago, purchased a new 3-1000z, but haven't had to
replace the original yet.
