Hello and thanks for the read. I have an ERC (Electronic Research Co.)
Oven-Crystal in an 8 pin octal base can.
Does anyone has a lead to a site where I could find which pins are for the
115V AC heater, +V and it's ground and at what voltage range to make the
1MHz xtal oscillate, and which pin for it's output.
I am trying to adapt this unit to fit inside a Motorola R-1201A signal
generator that is missing the original Xtal unit.
Thanks for any help.

Is this a complete crystal oscillator or simply an oven-ized plug-in
crystal unit? If its a simply oven/crystal unit, there won't be any Vcc
voltage. Try and open the can, remove the crystal, then map the xtal
socket pins to the octal plug. Some of their ovens are dual-voltage
(e.g. 6v and 12v DC). You also may be able to actually see the oven
windings going to the socket.
