[Amps] Best way to drop fil V on L7

[carl seyersdahl]

John: altho I'm not familiar with the L7, I did rewind the fil choke on an
SB200  with 18 ga. wire and it dropped the fil voltage about
 3to 4/10th. of a volt, which of course it was way too high anyway.
 that amp was last heard of going strong somewhere .!! that was two years
ago.
