Hi

I'm not sure if anyone is familiar with the greenvalve amp: http://cl.ly/3n0b380j3i1Z1V1M0R2D/o https://greenvalve.wordpress.com/the-maxim-gm70/img_6620/
What I don't like about it is that it still uses some large and heavy chokes..

I've reworked it and was wondering if one of the tube experts could tell me if I made any mistakes. I believe the e-choke on the -100v line can be replaced with a resistor? But what value?
I'm not sure why in the Greenvalve the 826 filaments are powered with 27V 4A, the sheet says 7.5V 4A.
