Default Re: Pye P114BQ Jewel case Speaker transformer

I have an Elstone MTO replacement output transformer from a Pye P131MBQ, which has a DL96 output valve as does the P114BQ. The transformer mounts on the speaker and being a replacement type has ratios of 80:1 or 42:1. The P131MBQ + MTO used 80:1. Primary resistance of 770 ohms for 80:1, around 350 ohms for 42:1.

The trademark Elstone green paint is peeling from the sides of the lamination clamp, which appears to be galvanised underneath. 8 plus p&p if interested. I can take a photo if you want more detail.
