25Z6 Rectifier to Solid State Conversion?

1N4007 across pin 3 and 4 (stripe).

Note that the resistor will need to be at least 10 watt, (15 W would be better) .

Unless you have a lot of power resistors, you might get the tube before you get the resistor(s).

Thats correct. I meant the diode across 3/4

Yes, I used 2 10w resistors for 80ohms.

The SS replacement I made seems to work fine! Getting more or less the right voltages, HV and a raster now.

If you didn't add a B+ dropping resistor or bucking zeners on the diodes, your voltage is going to be high. That's generally not a problem short term as long as you aren't stressing the electrolytics or your HV isn't too high.

I didn't add a zener or dropping resistors. If anything the LV supplies are 8-14V lower than the numbers I have in my Rider's. May be due to the rectified voltage coming off the Selenium being a little low. I will probably end up dropping a 1n4007 to sub that out too. Will definitely be using a dropping resistor there.
