For the original Williamson amps, the partridge transformers were well known not to oscillate in a properly built circuit. They were also better built than the average transformer. you get what you pay for in transformers, read what Mike Lefevre said a couple years ago in Vacuum Tube Valley and here on the asylums about the difference between a good output transformer and a bad one. Transformers are not designed for a brand of tubes ever to my knowledge and as Paul Joppa pointed out a while ago, you can make a tube in many ways, it is the way that it meets the tube curve specs that makes it a 6L6 or 6BQ5 etc. not what it looks like.
