1750V

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com PRIMARY 1750V SECONDARY YEL BLK COM TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • Designed for drop in replacement of original RED 4000 CT Ohm units such as VOX1 AC30 Vintage (P-TVO30V) 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". Open style with minimum 12" long primary and secondary leads Frequency response 70Hz - 15KHz (0/-1dB reference @ 1KHz) Distortion is less than 2% @ 70Hz GRN WHT BLU Typical 4000 Ohms 8 & 16 Ohms 30 W DCR Primary Yellow-Red Primary Red-White Secondary Black-Blue 70.37 Ohms 70.30 Ohms 0.720 Ohm ER RM z B V FO 5KH CT 16 Ω 1 0 50 17 ANS0Hz - : 400 -Ω8 Ω TR S 7 HT OM ADA O ATT - W : C N DI 30 W- RED - BLU N CA U I N A E EL GR Y K BL T DA E D MA C WHT BLK E D Inductance Impedance Primary Yellow-White Secondary Black-Green Secondary Black-Blue 16 Ohm 70Hz-15kHz 30 WATT ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power 8 Ohm @ 1.0 kHz, 1.0 V OC 6.30H 40K Ohm 19.66mH 132.95 Ohm 35.32mH 233.50 Ohm A G RED GRN YEL BLU Leakage Inductance Primary Yellow-White @ 1.0 kHz, 1.0 V SC 5.14 mH Dielectric Strength Temperature Range 2000VRMS -40 to 105 degC NOTE: ALL LEADS 12.0" OUT MIN.
