[Boatanchors] Re: [Heathkit] more DX-100 questions for Dummies

[Peter Markavage]

I see you mentioned "dip", but do you "load"? Coarse loading and Fine
loading, page 53 instructions
Grid current: use 0 to 10 MA scale.
Driver Plate current scale not used for tune up but useful for
information purposes (i.e. how is the driver performing, high current,
low current, no current, etc.)
Page 50 to 52 seems to have all the info you need for tune-up.
