I don't think that's his problem. You have to check voltages there before
replacing those...I tried on
mine, even though I had doubts..turned out to be a waste.
No secondary voltages off the fly...bad fly? B+ on fly and collector voltage
drops at power on to below
100v. IHVT secondaries start to come up a few volts, then shuts down in about a
second.
On mine, I replaced CR4118. I found some open caps that I thought for sure
would fix this.

Direct view CTC169
Power supply is not firing up. I cannot find any shorts or heavy loads
on
the output side.
I've tried watching it on a scope and bringing the AC up slowly, not
even a
twitch.
Has raw B+.
I haven't had many CTC169s, does anyone know of any common failures in
this
supply?
Looks like a thousand or more tips in the tip section, will take me a
month
just to sort through them.
Thanks
