Got a sack of mini relays made by Pickering used by Neve and Audix if
you want a few, only problem is there're 24 volt ones....

Got loads of suitable relays here too.

Not a lover of relays in a signal path, though.

We had an inline monitoring 48/4/2 Neve at Thames with thousands of the
bloody things always giving problems. ;-)


**I'll bet they weren't decent, hermetically sealed, gold contact types,
nor were they used to short the signal to earth. If such relays are used
in that type of application, they almost never exhibit problems.



** Pickering (of the UK) relays are ALL reed types - so have glass encapsulated
contacts. They feature Mu-metal shielding and are rated for millions of
operations - certainly not a cheap component.

They aren't, around 5 quid (10 AUS dollars) when i asked last, in small
quantities!..



Whenever I see a product with those clear topped, non-sealed DIL relays,
I know exactly what needs to be done. When the relay is replaced with a
proper one, I never see the job back. There are relays and there are
decent quality relays.

** The non sealed types I have come across develop bad contacts ( high
resistance) and cleaning them is PITA.

Agreed!...
