In Reply to: Buying a tube tester...... posted by thermionic addictions on February 28, 2007 at 11:43:26:
Weston 981, Type 3
It's the easiest of all testers to restore. It's built like a battleship. It is also tightly enclosed with no slot switches and uses standard switches and parts. There were alot of them sold and this tester was the standard at the National Bureau of Standards. It only has three or four electrolytic caps to replace. The maximum transconductance that it will measure is around 12000 umho so if you read a lot of 417As or even 6DJ8s if good will read off the meter scale. Try to find one that has not spent most of it's years with the lid off. If paint has been rubbed off the switch plate then you will know it's seen alot of abuse. The sockets for the most common tubes like the 6au6,12ax7, 12au7, 6sn7, 5U4, 5Y3, 6L6 maybe worn to the point that you have to replace the sockets. Look for one with an intact meter that the needle rests on the left. I like it much better than the Hickocks that are really pricey.
