++ on H-K short. recently had a Zenith AM-FM with a shorted
12BA6 IIRC. Hum & distorted audio.
Warm up & pull each tube one at a time EXCEPT audio out & see
if one makes it go away. After that its checking any new work
for proper values etc. EVERYBODY makes mistakes !!
BTW the rectifier should have a dropping resistor after it & the
selenium unhooked at one end.
