Welcome back Peter. You and ur dad sure did OK. I knew I would get a
comment from someone as soon as I mentioned the 6L6. Unfortunately, too
many of the current crop of engineers think that is some sort of highway
marking...my EE son included until he bought a KT-88 guitar amp.
I used three 5881's in parallel in my old dual 4-1000A screen supplies.
Didnt know any better then...they worked just fine ( I was buying bulk
NIB surplus 24 in a case for $10) . If I used them today Ian would have
me castrated!
