KB 214 "Transportable" radio

[Crackle]

I have found a spare U10 rectifier valve I had spare and now the HT is up to 247v, I think its rather too high now. So that proves the rectifier is not very good, but I will probably keep the 506K in, which was slightly better than the original DW2, so as to not stress other components too much.

I have also found a data sheet on the AC064 http://g3ynh.info/valves/old/Data-Books/...G-p046.pdf
