Brutus	Re: Hammond Transformers Yes, that is basically the difference. The "C" is the universal while the 125H has a specific primary of 10K and the 125J has a primary of 2.5K or 4K. I've had good luck with Hammond universal trannys but feel that I'd go with something optimized for a specific impedance instead. However, if you need 5K instead of 4K then the universal might be the better deal. Also, I noticed that the universal tranny doesn't have a freq rating (or at least one that I could find). But the specific impedance trannys do, that being 150Hz-15KHz at full power. Interestingly the lowest note on a guitar is 72hz if I remember correctly. When in doubt, all else being equal and equally unknown, go with the heavier tranny by weight. The response you loose with a light tranny is usually in the bass, and strong bass needs lots of iron.
