Could these work as a poor man’s Peerless s-217-d?

I just bought a big lot of old transformers for virtually nothing. After going through them, these two stuck out to me as possible s217d substitutes. A little low on the primary side 9k ohm ct, and a little low on the secondary 300/330 ohms. But they both have the tertiary feedback winding at 22 ohms, and I believe the s217d is 24 ohms. Would these work in a pinch?

2nd pic indicates they only have a limited frequency response: +/- 0.75dB from 300Hz to 3.5kHz

These specs are often grossly understated, though not always. Worth testing to see how low/high they go. Probably not 10Hz to 40k like the Peerless, but maybe good enough?
