Hello,

The rotating selecter must be placed in "DIODE" position to test small current diodes, as Ed says for example, in an EABC 80 or in a 75.

You place this selecter on "REDRESSEUSE" position to test one EZ81, one 80... The test current will be higher. Take care and avoid to test little diodes on "REDRESSEUSE" position !

The switch must be placed on "FAIBLE" to test tubes used in RF sections, or preamplifier (ECC83, 6D6,...) and must be placed on "FORTE" to test powertubes like EL84, 42,...
This for the cathode emission test.

Pay attention to the differences between the 751 and 752 Centrad models, they are not identical. The 752 is more sophisticated and has a different way of use... On simple cathode emission test, they are similar.

I own the complete manuals (scanned, in pdf mode) for this two appliances, and I send it by mail, on request, gratis ! All Centrad manuals are in french, I can help if you don't understand but I can only write my answers in english !

Greetings
Thierry
