Bought a capacitor leakage tester, custom made, from ebay. Trying to replace two OB2 voltage regulator tubes (107 volts each) with two 110volt zener diodes, 5 watts, wired in series, and reverse biased, as required. Circuit stabilizes , after slowly climbing, at 238 volts; should be regulated at 220. Also, zeners are quite hot after several minutes. Any comments, or suggestions? Thanks.
