AirKing 4000- 500M and 300M resistors
#2

I looked at the schematic on Nostalgia Air.

Where they put "50M, 300M and 500M" they mean 50K, 300K & 500K. In other words, 50,000 ohms, 300,000 ohms, and 500,000 ohms respectively.

I don't know why some manufacturers did this. It seems that prior to WWII that there was no standardization of electronic terms when it came to resistors. In this case, they are referring to the Roman numeral M which means 1000. Notice there is a resistor where the "MEG" is written out. R1, can't quite make out its value on the NA schematic but it is written as MEG, not M. Yes...confusing. Icon_crazy

Oh, btw, asking for parts is an ad and should be in the Wanted Ads section. Thanks. Icon_smile
