1167959 2011-01-08 20:29:00 Or these really strange capacitors I have too. Would love to know what they are, will post a photo.

Here's the photo of these strange capacitors.

I have never seen these mentioned in a book or seen them in any equipment either.

I am guessing they are quite old, probably used in valve or early transistor radios or something.

1167961 2011-01-08 23:09:00 I get a lot of stuff very cheap from the Nelson recycling centre, such as I needed a NIC got one for 50c installed it found drivers and away it went. You can find all sorts of useful stuff there. Found a brand new still boxed door handle and lock set with 5 keys cost me $3 sold on trademe for $75 and that's just one thing that springs to mind gary67 (56)

They appear to be precision caps for tuned circuits and they or their ilk were commonly found in valve TV tuners and high quality communications equipment. They date to the late 50's or early 60's and probably fell off the 'preferred component' market in the late 80's. No doubt they are still made or still around in small quantities though for special applications. If they do not have a value printed or colour-coded on them then they are almost certainly for OEM manufacturing.

The top one looks like it is labelled 220pF.

1167963 2011-01-09 11:45:00 That makes sense, someone on Badcaps.net said they are "tubular ceramic" and also linked to a website of a manufacturer, so It seems this type are indeed still used for something.

The ones in the photo all have values written on them in picofarads as you saw, and also a coloured dot (some red, some black). Not sure what that means though.

And yes, some are a bit different and have a 5-band colour code marking instead of a value printed.

and where do you suggest that Agent_24 buys them from?

and what do you do with the rod that passes through the centre of each card?

I bought a set 6 across X 4 vertical in ChCh coupla years ago...$80. Worth looking on trademe.
You take out the rod (that goes through the bottom of the card).
