rewiring Avo two panel tester

[Excessive Leakage]

Hello

I'm new to this forum and read this thread with great interest. I have recently acquired a two panel tester, but the plug was brittle and shattered in transit. I had spent 3 hours or so glueing it back together before I found this thread - Doh!  I have quite a few old B9 valves that I'll never use and I think I'll sacrifice an 'iffy' one (e.g. top anode cap missing) using cellulose thinners.

I'm sure that I have more than one 'iffy' B9-based valve, so if anyone would like one for its base please let me know.

BTW all but one of the resistors read within tolerance, but the waxy capacitor was shot and had to be changed. I also noticed that the voltage selector was set at 230, rather than 240v.

Thanks

Isn't 230V the new standard (was 240V)?

I've just measured the voltage where I live and it reads 235v. It was 240v recently.

Out of interest, isn't US voltage going the other way, i.e. higher?

The standard (since about 1950) is 120V +/- 5%, or 114 to 126V. In practice, the power companies have always tried to stay as close to the upper limit as possible, to maximize power delivery through the existing transmission network. Voltage here has been 123V since about 1960.
