of 50-100 H should be fine. A cheap solution is one of the antique vibrator transformers that were used in power supplies of car tube radios. Look for one from Stancor or Merit rated 70 mA at 270 V, preferably potted into a mu-metal case. Their inductance at 5-7 mA DC is about 80 H, and DCR is 400-600 Ohms. They have high quality low capacitance winding with insulation between each layer of wire. I used those in a different project, 71A transformer-coupled to PP 2A3, and was very happy with the result.Grid choke has to be 500-1,000 H, and as it works without DC current, it usually has gapless permalloy core. Mike of Magnequest offers those, check his forum here.
