Tube testers
« on: 8 Aug 2019, 08:55 pm »
Hi all,

I have an opportunity to acquire a couple of portable tube testers from a nearby university. Since I am unfamiliar with these devices, I was wondering if anyone could provide any information about them as to their usefulness, etc. I assume they are in good working order.  Many thanks.

WOW nice.
Sorry I cannot offer you any advice about either however a good place to start is by researching the MANUAL.

The Precision is the one to buy if you can only get one.  The Precision 910 is a great tester for older radio tubes (not newer tubes really).  It is "dynamic" and not emission.  It tests the tube more like it is in circuit than an emission tester does.  The Weston 774 is an emission tester.  It's cool, but it is just a go/no go tester for emission.  That said, Weston made good gear and I love anything with the 4/5/6 pin socket that their testers used.  Neither will test 9 pin miniatures.
