Product Reviews
These little gems are the best kept secret for interstage transformers. Don't be put off by the Hammond brand name. Has Hammond made some duds in the past? Absolutely, but these are not. I made a driver circuit for a 211 tube with the 126B and it performs wonderful. If you frequent DIYAudio and Audio Karma, only believe about 25% of what you read from the "experts". These are as good as any other interstage out there in my opinion.
