Description: This is a larger, multi-purpose version of the original single ended, 5W output transformer used in Harvard, Champ, Vibro-Champ, Tweed Princeton, and Bronco Style amplifiers. These can be used as an upgrade for these amplifiers as well as others like Marshall Class 5, Kustom Defender 5H, Vox AC4C1, Vox AX84 P1 Extreme, Epiphone Valve Jr and more. It can be used in higher wattage, single ended, amplifier projects which require up to 15W. They can be used with 6V6, EL84, EL34 and 6L6 output tubes. These can also be used with twin 6V6 or EL 84 tubes wired in parallel. This will provide increased headroom and clarity when used with single 6V6 and EL34 stages. These feature 5K & 8K  Ohm primary impedances and 4/8/16 Ohm secondary impedances. If these are used as an upgrade in original Champ style amplifier chassis, they may require chassis hole modification since they are slightly larger than the original. This is a paper wound output transformer just like the original vintage to reproduce the perfect tone!
