I'm out of date... Can anyone explain how you know which direction to read a

6 band resistor in? There doesn't seem to be an obvious asymmetry...

Cheers

Left to right. (Yes I know, I know). Bring back "Body-Tip-Spot" is what I say.

Oy! I don't look like a capacitor, although I am becoming a little rounder than I was.

Opps. ye shed door is ajar. Wrong planet!

Pigs for the end breaking off the swiss-roll though, if you pulled on the lead when soldering.

What was the name for these? Polyethylene foil and a cement dip AFAIR, but they had a name too?

[Bob Eager]

Are we talking abiut the same thing? These were rectangular, flattish, with rounded edges (typically about a cm per side, 2-3mm thick, wires from two of the bottom corners, horizontal stripes. Polyester ISTR.

On 17 Oct 2009 23:13:34 GMT, Bob Eager had this to say:

They were modern things. Proper condensers (mica) were maybe 1" x 3/4" x 1/16" and dipped in brown wax, or encased in brown bakelite (engraved with the value) with large flat tags sticking out of the ends.

Or Hunts/TCC paper ones in an aluminium tube with rubber seals in the ends.

Then of course there were wet electrolytics that had to be kept upright...

Mylar - I think those were mylar film. Or possibly ceramics. Mullard made em IIRC.

remember at that time..yes. its coming back. You could get stripey humbugs that were coil wound plastic, then mylar film, which was better, and polycarbonate, which was way best of all, because instead of a coil (flattened) they interleaved the plates.. Very low self inductance AND they ground the ends down to precision values.

[Bob Eager]

Yep, seen (and mostly used) all of those too. But not as pretty...

That is *OLD* .

Really ? Never new that. That could explain one or two things ...

Presumably one only ever encountered them hard mounted on (pre-war) wireless set chassis.

Oh, so that's what the "virginity" was all about. I learned 6-7-8-9 as "...But Violet Grey's Willing."

Sorry - been on the PPs and BAs.

That's the ones! They *were* polyester after all!

You could have left them charged up...

We were taught it a little bit different. I'm sure it was 'rape' instead of 'root', and the last four words were 'but virgins go without'.

I don't remember it being 'bad' either. But can't think what it was.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "John Whitworth" saying something like:

Bad Boys Rape Our Young Girls, But Virgins Go Without. Throwing sensitivity to the wind, the other version substituted 'Black' for 'Bad'. I've no doubt there's a perfectly acceptable but dead boring version out there.
