Hi Matt,
The transformer is likely a Hammond 125h. See the following link:
https://www.hammfg.com/electronics/trans...audio/125h. Plate to plate impedance for a Type 19 in push-pull is 10KOhms. You can likely scavenge an output transformer from the many Philcos that used a pair of type 41, 6K6s or 7B5s in push pull. Plate to plate impedances for all of these tubes is 12KOhms. The mismatch is not critical.
