Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750F TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER PRIMARY • BRN • • • • • 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 7" long primary and secondary leads Frequency response 70Hz - 15KHz (0/-1.5dB reference @ 1KHz) Distortion is less than 3% @ 70Hz SECONDARY GRN COM RED 6950 CT Ohms BLK 8 Ohms BLU 70Hz - 15kHz 15W ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 6950 Ohms 8 Ohms 15W BL 17 50 C GRN U - 15 RE W G R D -B 7 0 N - R N H zBL : 6 15 IN K: 95 kH CA NA 8 0  z DA CT MA DE F BLK DA TE B DCR Primary Red-Brown Primary Red-Blue Secondary Black-Green 97.36 Ohms 97.36 Ohms 0.409 Ohm BRN A RED D G Inductance Impedance Primary Blue-Brown Secondary Black-Green @ 1.0 kHz, 1.0 V OC 3.99H 24.8K Ohm 8.71mH 66.28 Ohm Leakage Inductance Primary Blue-Brown @ 1.0 kHz, 1.0 V SC 7.03mH 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 Keithley 2010 DVM Hp4192a impedance analyzer BLU NOTE: ALL LEADS 7" OUT MIN.
