For sale is a pair of brand new, never used, PARTRIDGE TK7441 Tube Single Ended Output Transformer Par. I bought these transformers from a UK dealer 4 years ago and have never put them to use, so they are new and unused. This transformer type is considered to be one of the best existing output single ended tube audio transformers.This is the same Partridge transformer type as the type TH4663, also marked as TK4519 and used by Jean Hiraga in his 300B SE amplifier. Transformers & Rectifiers Ltd from UK have purchased Partridge transformers several years ago and are now manufacturing Partridge designed transformers with Partridge specs nowadays. TK7441 is their equivalent number to the original Partridge number TH4663. Transformer specifications are: Power 40W, frequency response 20 Hz to 100 kHz, Primary Impedance 2.3 or 3.5 kOhm, Primary inductance 26 H, max. primary current 130 mA, insertion loss 0.26 dB, secondary 4, 8 or 16 Ohms. Each transformer weighs almost 5 kg (12 lb). The buyer pays for insured shipping of 15 kg (33 lbs). I shall ship to anywhere around the world from my location, which is in Slovenia, Europe. I accept either Paypal payment with a 3.7 % surcharge or, if within Europe, a transfer to my bank account. Payment can be in US$ or an eqivalent in EUR.
