And, just what do you plan to use it for? The last time I used a tube checker was in 1970 and tubes were already becoming obsolete THEN.!
Tube testers only test receiving tubes. If you have the manual, then it should give the setup for each tube you want to test… the grid bias, the B+, the ‘mho’ (unit of transconductance, the opposite of the “ohm”_ and, let’s see.. it will give the filament voltage and the beta of the tube.
Like I said at the beginning… Just what do you plan to USE it for… it’s way too light to use as a small boat anchor.
One of these sold with a manual on eBay recently. Perhaps you can contact the buyer and offer to pay him or her to copy the manual for you. See the links below.
