1750X

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750X TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • Designed for drop in replacement of original units such as Marshall1 JCM 900 (P-TM9100O) 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". Frequency response 50Hz - 12KHz (0/-1dB reference @ 1KHz) Distortion is less than 1% @ 50Hz ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 1700 Ohms 4, 8 & 16 Ohms 100 W DCR PIN#4-2 PIN#2-6 PIN#4-6 PIN#23-21 PIN#23-16 PIN#23-14 16.58Ohms 16.04Ohms 32.58Ohms 0.130Ohm 0.170Ohm 0.230Ohm Inductance Impedance PIN#4-6 @ 60Hz, 10 V OC 14.54H 5.61K Ohm Leakage Inductance Primary Blue-Red @ 60Hz, 10 V SC 2.66 mH Dielectric Strength Temperature Range 2500VRMS -40 to 105 degC Dimensions A 3.750” ±0.063 B 3.125” ±0.063 C 4.010” ±0.125 D E F TEST CONDITIONS Measurement instruments: D scope series iii audio analyzer Wayne Kerr 3255B with a 3265B 3.125” ±0.063 2.500” ±0.063 2.268” ±0.063 0.219” ±0.015 0.394” ±0.031 TYPICAL TEST CIRCUIT PRIMARY Keithley 2010 DVM Hp4192a impedance analyzer G H R S/ SECONDARY 2 RL * All graphs input level 27dBu @1.0KHz reference. **The results are typical and are subject to normal manufacturing and electrical tolerances.
