Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1760K TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • PRIMARY Designed for drop in replacement of original units. 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 9" long primary and secondary leads Frequency response 70Hz - 15KHz (0/-1dB reference @ 1KHz) Distortion is less than 1% @ 70Hz SECONDARY GRN 8 Ohm BLU YEL 4 Ohm 4000 CT Ohm WHT 2 Ohm BRN BLK COM RED 50 Watts 70Hz - 15kHz ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 4000 Ohms 2, 4 & 8 Ohms 50 W Hz B  5k 0 K z -1 CT 4 /8 DATE 7 6 70 H000  /2 / WHT 1 T S U : 4 OM C T L W A -B N: 5 0 -REDL/GR RN /YE DA B HT A AN K/W IN C BL ADE Y EL M DCR Primary Brown-Blue Secondary Black-White Secondary Black-Yellow Secondary Black-Green C 89.43 Ohms 0.091 Ohm 0.183 Ohm 0.219 Ohm BLK IN D O N TU R M M AC H A NU F MA @ 1.0 kHz, 1.0 V OC 5.38 H 33.8 KOhm 8.53 mH 91.74 Ohm 17.59 mH 172.15 Ohm 33.62 mH 298.4 Ohm Leakage Inductance Primary Brown-Blue @ 1.0 kHz, 1.0 V SC 3.136 mH Dielectric Strength Temperature Range 2000VRMS -40 to 105 degC RED D E BRN G Dimensions A 4.063” ±0.063 B 3.238” ±0.125 C 3.485” ±0.063 D 3.500” ±0.063 E F G 2.000” ±0.063 2.560” ±0.063 0.177” X 0.300" ±0.015 TYPICAL TEST CIRCUIT PRIMARY Keithley 2010 DVM Hp4192a impedance analyzer A NOTE: ALL LEADS 9.0" OUT MIN.
