I have an Eico 667 that hasn't been used in a number of years.  I brought it back up very slowly and it appears the filters are OK.  Power supply ripple seems nominal.

However I recently had cause to check a 6AQ5.  It barely moved the "merit" needle.  I pulled another
(used) one and it checked the same.  Altogether I checked 7 or 8 6AQ5's 
(all pulls).  They all barely moved the needle in the same way.   I find 
it hard to beleive they were all that bad.

Other than buying a new 6AQ5, which may not be needed should the tube checker be bad, does anyone know of a way to check the performance of the 667?

Your attention is appreciated,
73,
Ray, W4BYG
