Labratory

This L. & N. Anthony - Pattern Wheatstone Bridge serves as the external calibration decade and bridge for the V.T.S. Laboratory. This gives me the ability to confirm actual performance measurements of any decade in the lab with "Rock of Gibraltar" short & long term stability. (As compared to my imitators who stick the tube in whatever tester they have on hand and hope for the best.) Why are things so different at V.T.S.? Because V.T.S. was never started as a "get rich quick" scheme or "Let's jump on the bandwagon".

Laboratory grade tube rigs have separate plug in modules for the lowest possible capacitance (as compared to the high capacitance of the many paralleled sockets in a typical service tester). Here the 4 pin module holds a Sylvania Globe 45 tube. V.T.S. rejects many inferior tubes that would be passed on and sold as good by others.

The warm colors and smooth lines of this truly classic and elegant equipment can soften the harsh monotony of many long hours spent in the lab.

(For the technically minded, yes I do run high precision digital backups on heater voltage, etc..., when needed.)
