Quantity in Basket:
Shipping Weight: 4.00 pounds
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.
