Remove the feedback and compensation caps per Joe Rosen ,convert to triode if you can , stick to 7199 and I liked ole vitQ 0.1/630v in coupling position and lesser PIO s in input pentode decoupling. The about only "magical" St-70 I heard was with original slightly upgraded board and 7199 tube. For whatever reason it had that elusive tonal quality "modernized" versions lacked as good as they were.
