[HomeBrew] tube sockets

[Helmut Usbeck]

Greetings,
I am in the need for Three (3) 5 pin CERAMIC tube sockets.  They must be
of the type
that has tab or saddle mounts.  I have the plate type, but are too large
and clumbsy for my application.
Does anyone know DEFINITELY of an outlet where I could get
these?  If not
does anyone have any I could purchase.  They don't have to be new, used is
OK.  Sockets of other material is not OK.  Thanks!

Regards,
