WTB:Balancing Input Transformers

[loach71]

Folks:

I need some 15K-15K balancing input transformers, OCTAL base.
Old BGW part number 0900-9250. I've tried BGW but no luck.
Any ideas?

Thanks!

Altec/Peerless 15335 - 15K/15K, can and core grounded to one side of input. Or the 15335A, which grounds can and core to independant pin. Fairly common on eBay. So common I suspect some have been passed around quite a bit by the clueless. 'Recently removed from service' or 'guaranteed' recommended. I happened to test a pair recently, they read around 650 ohms DCR, and +/- 1dB from 32-20kHz, rolls -6dB below 32Hz.
