Subject: Re: [Amps] SCR to adjust 240v to 200v
I can sell you a filament transformer from a SB-220 and that would solve the
filament problem.
## wont work. The henry runs the fils in SERIES. So they use a 10 V @ 15A
fil xfmr !
It truly is a stupid idea, since then u can never operate the amp with just one
tube installed, like
when trying to isolate a tube problem. TL-922 does the same fubar.
## He doesnt need a fil xfmr any way. All he requires is a BUCK xfmr with
a 120 or 240 vac primary...and a 40 V sec
and with a sec current rating at least equal to the max normal line current his
amp draws... like 15-20 A
