[Hallicrafters] Muffled audio cleared up

[Phil Atchley]

Hello all
Last night I was able to clear up the weak/muffled audio in the SX-71.  I
had tested all tubes in a (borrowed) tube tester.  However, replacing the
6K6 audio output tube cleared up the audio.  It now has very good, clear
audio and PLENTY of it!  That tube must have been gassy or sumthin'.  Now
I'm doing a thorough burn-in while doing the cabinet etc.  Then it will
receive a 'final' RF/IF alignment and put into fulltime service.   (It sure
sounds nice)
