This is the same custom transformer that is used in the Granite Audio Model #770 preamp. It is also the ideal transformer to be used with the 770 Power Supply PCB for sale on this site. The exposed bolt ends are 8-32 thread and are useful for mounting the transformer on standoffs. This leaves clearance for the wire leads without having to drill wire access holes in the chassis. The #770 preamp uses six 12AX7 tubes and one 6X4 tube. You can use different tubes as long as you don't exceed the current and voltage specs of the 770 transformer.

Specifications:
117VAC Primary @ 60Hz.
325-0-325 VCT secondary @ 40ma.
5 V @ 2A
6.3 VCT @ 2A
Mounting centers 2" x 2.5" Horizontal.
Leads are 12" long.
Overall size 3" x 2.5" x 2.8" high.
Weight 2.5 pounds.
