Primary = 10,000 Ohms, [Red, Yellow]

Part Number 20A18 Interstage Transformer.
Used as interstage to match single amp tube to push pull grids for audio amplifier.
This transformer was placed in a circuit, then I re-designed the circuit for additional audio output.
It is in perfect operating condition.
