In Reply to: not in my roll or obsolete settings charts.... posted by gortnipper on January 12, 2007 at 16:58:11:
Tube: 2A3
Fil: 2.5
Selectors: 4130-2000
Bias: 74
Shunt: ---
Mult: X4
Press: S5
Min Mut Cond: 475
Notations: (none)The 752(A) is capable of checking a 300B but I've never seen formal set-up for it. Since the TV7(x) will check this tube and has complete set-up data, it shouldn't be too difficult to reverse engineer set-up to a 752. Fortunately, I haven't been seduced by a 300B yet so this work will have to wait for someone else.
The 752 is not capable of testing a 211 or 845 even with a socket adaptor. Applied voltages are WAAAAAAY too low (~150V max). I'm aware of no vintage tester that can handle these ancient transmitting tubes inc. the military testers. I've seen some recent boutique testers that can but they're pretty much custom devices. Since you're going to need ~800-1000V to test these beasts, you're probably best off devising your own tester and set them up and test by the book.
