1760W

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1760W PRIMARY TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • SECONDARY BLU 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 YEL 16 Ohm GRN 8 Ohm RED WHT 4 Ohm 2000 CT Ohm BRN COM BLK 70Hz - 15kHz 100W ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 2000 Ohms 4, 8 & 16 Ohms 100 W 13.24 Ohm 14.44 Ohm 0.110 Ohm 0.175 Ohm 0.279 Ohm Inductance Impedance Primary Brown-Blue Secondary Black-White Secondary Black-Green Secondary Black-Yellow @ 1.0 kHz, 1.0 V OC 4.55 H 30.4 KOhm 11.46 mH 221.4 Ohm 23.64 mH 421.5 Ohm 49.44 mH 786.2 Ohm Leakage Inductance Primary Brown-Blue @ 1.0 kHz, 1.0 V SC 1.280 mH Dielectric Strength Temperature Range 2000VRMS -40 to 105 degC TEST CONDITIONS Keithley 2010 DVM Hp4192a impedance analyzer B L M AD GRN C IN D ON TUR M M AC HA NU F MA G BRN YEL RED D E F BLU A G NOTE: ALL LEADS 9.0" OUT MIN.
