No more PCB's are available.
Unless you find some 19J6 sitting around, your going to need to go 9 pin and 17EW8 or similar.
This is the schematic for the 9 pin version.
The only real substitution from the original parts list (besides any of the optional stuff.) is the 390omh resistors in R2 & R8.
This is the current parts list I have on order for mine. I subbed 63volts 470uF 20% general caps for the audio ones suggested because they were back orderd. Not saying it's all correct, but I had a hell of a time figuring out what I needed and what I didn't from the 370 page thread :)
