These transformers have 1:15 winding ratio as opposed to the 4722's 1:18 ratio. That means they have about 1.7dB less gain than the 4722. The impedance ratio is 200 to 45,000 ohms (as opposed to 150 to 50,000). The center tap is also here for either applying phantom or higher gain for ribbon mics, etc. They have a similar frequency response, and actually, being more modern transformers, they'll take almost the same level as the 4722 before they start to distort, even though the core is smaller.  With the difference in gain and other things, these won't sound identical to a 4722, but the specs are similar enough I'd call them electrically compatible....a circuit suitable for one of them will be suitable for the other as well. Ampex, Studer, Langevin, MCI, Helios, and others have all made products using beyer transformers over the years. They have a full range frequency response and sound great.

These transformer are soldered to a little PCB wafer that leads the transformer pins to the correct octal socket pins. Since PCB solder points aren't designed to take a lot of force, I recommend that you leave them in place in their sockets as much as possible, and try to pull as much as possible only on the base when you remove them, not the transformer itself. I made a made and sold a couple dozen or so of these here on ebay 5-6 years ago...I've never personally broken one or heard of someone else breaking one, but I do think it would be possible...you'll want to treat them with just a bit more care than you might with one of the original cans.
