1750N

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750N PRIMARY TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • SECONDARY BLK COM BLU Designed for drop in replacement of original 3200 Ohm units such as Marshall1 JMP, JCM 800(P-TM050) 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 11" long primary and secondary leads Frequency response 70Hz - 15KHz (0/-1dB reference @ 1KHz) Distortion is less than 1% @ 70Hz CT YEL 4 Ohm WHT ORG 8 Ohm RED VIO 16 Ohm 50Hz-12kHz 50 W B ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 3200 Ohms 4, 8 & 16 Ohms 50 W DCR Primary Blue-White Primary White-Red Secondary Black-Yellow N 50 kH z C T 17 0Hz - 1: 53200   7 S - RE DL : 4  6 TT W A H T YE : 1 A 5 0 - W O M , , VI O N A D U : C  CA L B LK : 8 I N B RG E O AD M VIO ORG DA TE Y EL C BLK 41.74 Ohms 43.14 Ohms 0.770 Ohm BLU E D Inductance Impedance Primary Blue-Red @ 1.0 kHz, 1.0 V OC 18.3H 112K Ohm Leakage Inductance Primary Blue-Red @ 1.0 kHz, 1.0 V SC 13.41 mH Dielectric Strength Temperature Range 1500VRMS -40 to 105 degC TEST CONDITIONS Measurement instruments: D scope series iii audio analyzer Wayne Kerr 3255B with a 3265B 1 RED NOTE: ALL LEADS 11" OUT MIN., STRIPPED .5" Dimensions A 3.125” ±0.063 B 3.350” Max C D 3.800” Max 2.500” ±0.063 E G 2.450” ±0.063 0.188X0.406 ” ±0.015 TYPICAL TEST CIRCUIT 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.
