1750R

Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 1750R PRIMARY TUBE GUITAR AMPLIFIER - OUTPUT TRANSFORMER • • • • • • SECONDARY ORG COM BRN Designed for drop in replacement of original 2000 Ohm units such as Yorkville/Traynor 1 98694 (A1301) 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 50Hz - 12KHz (0/-1dB reference @ 1KHz) Distortion is less than 1% @ 50Hz CT YEL 4 Ohm RED GRN 8 Ohm BLU BLK 16 Ohm 50Hz-12kHz 100 W B R 50 2kHz C T 17 50H z - 21000  ELECTRICAL SPECIFICATIONS Characteristics Input Impedance Output Impedance Output Power Typical 2000 Ohms 4, 8 & 16 Ohms 100 W Y EL DA TE GRN C DCR Primary Blue-Brown Secondary Black-Orange 25.72 Ohms 0.222 Ohm Inductance Impedance Primary Blue-Brown Secondary Black-Green Secondary Black-Yellow Secondary Black-Orange @ 1.0 kHz, 1.0 V OC 4.84H 31.2K Ohm 16.20mH 117.05 Ohm 31.28mH 219.30 Ohm 58.48mH 400.60 Ohm Leakage Inductance Primary Blue-Brown @ 1.0 kHz, 1.0 V SC 11.37 mH Dielectric Strength Temperature Range 2250VRMS -40 to 105 degC TEST CONDITIONS Measurement instruments: D scope series iii audio analyzer Wayne Kerr 3255B with a 3265B  : TS - BR NN: 4 6  AT R :1 A 0W ED , G 1 0 - R O M , O RG NA D U C A B L LK : : 8  I N C B EL DE Y MA ORG BLK BLU E D Dimensions A 3.750” ±0.063 B 3.936” ±0.125 C D 4.560" MAX 3.000” ±0.063 E G 1 BRN 2.813” ±0.063 0.203 X 0.375 ” ±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.
