Charles, Yes the Sophia Electric 91-05 is a beautiful sounding output transformer and my amp is tweeked out WE91a with Black Gates in the tube bypasses and Duelund couplers and I recently optimized the power supply with some help from one of the guys on the Audio Ayslum site so at this time I dont want to upset the apple cart of sonic goodness so the plan is to build a second amp with the AN output trannies. They are double C Core Ultra HiB. These are the version just below silver. Take a look at AN prices for their silver transfomers in pounds and then convert to dollars, you'll gasp in horror. But before I build the second amp I'll uninstall the Sophias and put these bad boys into service on my present amp. These AN transformers have a 2.7k primary impedance which is specifically designed to work with Audio Note speakers. I havent posted anything in my system thread for a while so I'll update it with more info about my 2nd amp.
Grannyring we need to compare notes on our polypropylene capacitors.
