Current Flowing Indicator.

Hi Joe - as I have mentioned before, I've been engaged in electronics and radio work since I was a youngster and over that time period, I have looked at all manner of cct. diags., but I have never seen the Greek symbol [lower case omega] ever used as a symbol for resistance - until now! Now if that symbol was in use in the 1920's - 1930's, that would explain it: my experience with kit from that era is very thin

Oddly, today I was at Spitalfields Antiques Market (its on every Thursday and I work round the corner) - sometimes (not often) there are things of interest.

One stall had obviously cleaned out the workshop of an old radio guy, and there were cards of resistors etc... guess how they were marked?

Oh, he wanted 5 quid a card. I passed...

EDIT: Just thought! I could buy one, measure the component value and then we'd know what the lower-case omega meant...
