[ProAudio] Western Electric 111C transformers

[Bob Katz]

I will definitely post my results.


But first I have to find a place in my crowded system to put these big 
puppies. They are certainly among the largest piece of audio iron I've 
ever seen. I don't understand how a telephone company in the middle ages 
decided to make a transformer with such amazing bandwidth!

Look what I just found on reverb:

So I guess I should be very glad I happen to have a pair that cost me 
nothing!


Best wishes,



Bob
