Curtis Mathes C20 Ctc 15/16 clone woes

Alright guys I'm going to come back at.

So basically I was wrong saying the fly back is shorted. Its totally fine.

The set has audio. There's static and changing the channel knob makes noise. Currently there's NO raster.

The most obvious first reason is a positive g1 voltage on the HO bulb. I went back towards the horz osc and the voltages were off. I'm going to fire it up and check B+ Rails, and re check osc voltages. I'm pretty sure the vertical is running because you can audibly hear it. Woot!

The CM clone fires up and produces Hv and a raster. It's kind of odd but the ho cathode current is only like 100ma and adjusting the efficiency coil wasn't changing it. Its producing like 20kv. Raster is pretty bright.

I will have to so some serious cleaning. You can draw a little arc off the hv cage. Most likely the hv is tracing through dust/carbon. The hv is pretty noisy but it's all working.
