Hey All,
After a long hiatus I'm back to this amp building for fun. My question is I have 2 sets of transformers from Allyn. They are Pacific.
For the Express the numbers are PT 2112 and OT 2113. For the Rocket they are PT 2111 and OT 2117.
Does anyone have the wiring schematic for the transformers? Not how to hook them up but which wire are what?
Thanks for any help.
Rich

Hi,
I'm building another Rocket with Allyn's transformers right now...
PT 2111:
Bl-Bl - AC in
R-R - 5V
Y/R - CT
Br-Br - 6.3V
Whi/Br - CT
Y-Y - 280v
Y/G-Y/G - 250v
OT 2117 (like A470):
Blu/Whi-Blu - Plates
Gr/Whi-Gr - Screens (UL only - not used in Rocket)
R - HV
Bl - Gnd
Brn - 4 Ohm
Or - 8 Ohm
Y - 16 Ohm
Cheers,
Greg
