1750P

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750P TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • Designed for drop in replacement of original units such as Marshall1 JMP, JCM 800 (P-TM0100) 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% @ 70Hz ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 3400 Ohms 4, 8 & 16 Ohms 50 W DCR PIN#4-7 PIN#4-2 PIN#2-7 PIN#23-21 PIN#23-16 PIN#23-14 82.25Ohms 40.70Ohms 41.47Ohms 0.351Ohm 0.506Ohm 0.725Ohm Inductance Impedance PIN#4-7 B C D @ 60Hz, 10 V OC 22.65H 8.62K Ohm Leakage Inductance Primary Blue-Red @ 60Hz, 10 V SC 10.30 mH Dielectric Strength Temperature Range 2250VRMS -40 to 105 degC E A Dimensions A 3.760” ±0.063 B 3.090” ±0.125 C D TEST CONDITIONS Measurement instruments: D scope series iii audio analyzer Wayne Kerr 3255B with a 3265B 3.130” ±0.063 2.500” ±0.063 3.128” ±0.063 TYPICAL TEST CIRCUIT PRIMARY Keithley 2010 DVM Hp4192a impedance analyzer E 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. 1 R S/ OUT 2 DISCLAIMER: Hammond Mfg. is not affiliated with Fender Musical Instruments Corp., Marshall Amplification, Yorkville/Traynor, AMPEG or VOX Amplification companies.
