help oldish multimeter

[robert the violinist]

Old Sparky thanks , i`ll try and understand it.  I used to be a chemist so we tended to ignore physics

Jeffrey`s correct 6k6 not 6k8.   6K6 will roughly half the power of the amp i think.

Update, i tried the new extech meter , followed instruction and got these readings for plate dcV and mA. Readings stable and meter display not varying much at all.
They seem a bit low to me but unsure.

Ive attached a section from the amp build manual. Its written by Barry Vyse who i believe worked for Marconi-Osram andthis is one of his amps or constructed in one of his amp workshops.
