CTC-5 issue

[Zenith26kc20]

Very interesting! When my 25MC233 had a 6BK4 failure high voltage went thru the roof! What is the high voltage on your CTC5? If I remember right they are not capable of ridiculous levels like my 25MC33 (close to 32 KV when the tube died). Sounds like yours went gassy.

The CTC-5 HV is around 20kV at best. One of the complaints everyone has about it. Whereas most of the other vintage color sets are around 25kV.

My CTC4 topped out at 22 kV before the flyback fried, with the tripler in place though I now get around 24.
