Restored an old Heathkit AA-1 Audio Analyzer

I believe the 1N60 is also a good choice.

Thanks Mike,great scan.Much appreciated! I've got a really battered VTVM (oddly enough,the meter is perfect:dunno:) that I was going to convert to the watt-meter,but could never find an original scale to copy.
 
I drive by the Old Heathkit plant every day !

I to have many vtvm's and a raggie one could become a watt meter with the right guidance

arts - how did the conversation mentioned work out ?.
