Got in w/ SMPS squeal,replaced HOT & fly.
Tested and noticed a creeping temp of HOT.Did electrolytics around driver,L4401
resolder
After mucho time noticed the drive pulse to HOT base @ half-power points to be
something like 10 usec.Can anyone refresh me[?] I've been all over NTSC sites
-no help.
My question is: What is pulse width in usec @ base of HOT in a sample
television receiver?That would be @ 1/2 power point or .707 of peak
Regards[?]
Pete
