Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750T PRIMARY TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • SECONDARY RED BLK COM Designed for drop in replacement of original units such as VOX1 AC30 Reissue (P-TVO30R) Constructed to look similar to original factory units (where possible). Material used & design specifications were kept as close as possible to the original part to preserve the stock "tone".
