I have obtained two Aristo D-2 units, one standard, one D-2 Hi. Both with broken tubes. I wanted to upgrade the tube to V54 anyway, so--I bought the package for very little. In checking the transformers--(I didn't want to buy a tube unless the transformer worked!)-I found the "Hi" unit produced about 1850 V, and the secondary had a resistance of about 3,000 Ohms. The standard unit produced about 1850 V also, but secondary resistance was 600,000 Ohms. Neither unit has shorted secondary wiring. Supposedly, the new tube will work in either unit. My question--is one unit bad, and if so, which one? I am going to adapt the good one to a Omega D4 (incandescent) Chromega, whose light output is pretty dismal.
Thanks
