Subject: [TechAssist] RCA PTK 195 blows horizontal output
Hello,
Here's my latest dog. An RCA chassis (M#P52927 / ch# PTK195M26B)
It blows the Horizontal output transistor after about 2 seconds.
I've ruled out the splitter; Changed the flyback, and the horizontal output
transistor (used original RCA
parts on both). Double checked that I had the right transformer for the chassis.
With the transistor out, I measured 169V at the collector terminal, in standby
mode. The horizontal output
circuit tests OK on my horizontal analyzer.
Any ideas?
