[Lafayette] Lafayette VTVM

[Ron via Lafayette]

Hi. I just purchased a Lafayette VTVM model 174. This is a pretty unusual VTVM. It is unclear if it was a kit or not.......
It is in mint condition but not quite working correctly. Although the case states just Model 174, it may indeed be a KT-174.
I have had this dilemma before. I purchased a KT-208, which is a signal generator/tracer, which may or not have been factory wired. 
The KT-208 is identical to the Accurate Instruments 154.

The VTVM is 'unusual' in that it uses a 12AX7 (which is marked on the PC board), and a 6BL8 alongside. The 6BL8 nomenclature is NOT marked on the board, so, I'm not even sure if it's the correct tube.The usual other VTVM tube is a 6AL5, right?

Yep, I collect VTVMs AND Lafayettes. Don't know why, I just do.
(also started collecting vintage metal detectors, sigh)

Any ideas???
