I recently bought an Orange Tube tester and have been going through all my Amps and modules.
I was very surprised to find that out of the 34 tubes in my 17 modules, 9 tubes came back rated worn.
Luckily I have a collection of tubes from when I was re-tubing Amps in the past and after testing all my used stuff I was able to find good matched tubes for replacements in all the modules.
I know there will be many here that have good collections of modules, so do yourself a favor and get yourself a tester or get your modules tested some place. you will be glad you did.
