Mojo Caps

[Skruffyhound]

Anyone recognize these?



Despite 3 huge parts orders recently, I found myself without 100K trimmers, and whilst ripping them out of my enormous pile of audio junk it occured to me that I could make a full mojo pedal for fun and as a test of case. Old pots/tropical fish/carbon resistors(huge)/an old danish telephone company box. Transistors may be tricky but I'll give it a go.

Anyway, these 80's audiophile caps are good values but they look a bit like Tants to me, can anyone tell me what they are, and if they are Tants, how the hell can I find the positive leg. There are other clearly marked tantalums in the same device, so they may be film but I'm suspicious. Can I test them somehow without destroying too many of them.
Thanks, Aston

They are tantalums I believe.
Some just have color codes, like those.

Thanks John, I guess I'll just have to try and find out the orientation by looking for clues on the board they came from and hope that some system becomes apparent. Actually, if they are tants then they are less interesting because tants and electros have the highest rate of ageing and I would risk building an effect that might decay in quality quite quickly. Oh well, pity.
