Default Re: Homebrew Valve Tester

Hi All,
The last thing I thought there would be trouble with was the module.
I did a search on E Bay for "Blue LCD Meters" and a company called Asia Engineer has them in stock.
The tester will supply 250v @100mA OK, the current is limited to about 110mA. The transformer shows no sign of stress as it is only used for a short period of time.
Thanks to others who have given their heater requirements, will hold those on file.
Regards
Mike
