++ 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. 73 Zeno LFOD ! |
