[WRL] 500B Manual

[Larry Rau]

You should invest the $10-12 bucks it costs for a good quality WRL manual
copy for the 500B/C

Try Peter Markavage... google search Manualman.

He makes very  good quality copies... and the service is good.

The original manual has a voltage chart, schematic,
theory of operation pages - stage by stage, parts lists, pictures,
proper operating conditions... grid drive, plate current, basic settings,
etc.

You  simply cannot properly overhaul, service, or operate a globe king
without out this manual.

*** If making interconnecting cables.. pay particular attention to the
schematics... because the pin-out does change between the various decks !

You can use a B or a C manual just fine...but the A or plain 500 manual isnt
gonna work for you.
Although you are better off with the B manual, because of control
integration in the C model.

"When in doubt - read the instructions"
