Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750W TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • PRIMARY 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/-1.0dB reference @ 1KHz) Distortion is less than 1% @ 70Hz BLU 2000 Ohm Typical 2000 Ohms 4 Ohms 100W WHT 4 Ohm BLK COM CT RED BRN 100 WATTS 70Hz - 15kHz ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power SECONDARY kH z W 15 0 50 z - 200 1 7 70H U : 4 CT DA B TE L -B T : 0W D H 1 0 -R E K- WDA N L A B R B CAN BLK MA DE IN C BRN DCR Primary Brown-Blue Secondary Black-White Inductance Impedance Primary Brown-Blue 22.8 Ohms 0.410 Ohm WHT @ 1.0 kHz, 1.0 V SC 1.31mH Dielectric Strength Temperature Range 2000VRMS -40 to 105 degC G NOTE: ALL LEADS 9.0" OUT MIN.
