I am sorry, we do not have any of the specs. If you could get use the specs, we might be able to build them for you.
The 4651A is described as “Ratio 1:2.3 CT 15K to 80K CT. Very large 100% Mumetal core and thick Mumetal can. Color coded leads. Can size 45 mm dia 52.5 mm high mounting grommet (Type 1231E) or 2 x M3 holes (Type1231I)”.
The 16402 was described as “23kCT/150+150 ohm output transformer for driving a balanced line from push-pull 6CG7 etc. 100% M6 core for high level capability and low distortion. Twin secondaries for 600/150 ohm outputs. Voltage ratio 12.4CT:1+1 Max dc per side of primary 20 mA. Supplied with end frames for vertical or horizontal mounting style.
These specs are the typical "can" mounting on a chassis, where the wiring comes out of the bottom, thru a hole, and wires to a hand wired tube chassis.
I would be more interested in a PCB mount, if possible, which could be soldered to the PCB, and covered with an optional metal shield of your, or my design. I can work with any profile transformer since it's a new, non authentic build. Suggestions welcomed.
shows the circuit. The transformer for the power supply should be a normally stocked item, isn't it?
