RE: 5755 and a ll1630 for preamp

So Tk what do think go for the e1148 the hyton topcat 6j5? That or 12au7. the 6j5 will like 250. 5ma is the problem. I got 9pins in though.

edit can't find my 6cm7 found a lot of 6dj8 and au7.only other option is double up the primary and run 12b4 at 10ma not sure if that will work I only fluke stuff without help. Iam only guessing the plate resistance is low enough to drive the trans in parallel. How I will test this is with phone and iem on the bench dont have a scope so the fb is unrealistic too until I get one.
