Pre-amplifier Output Transformers

Audio Note has always been advocates of the pre-amplifier output transformer. Instead of using an anode resistor/signal capacitor on the pre-amp output valve, they position a high-quality transformer on the anode. The result is an exquisite highly detailed sound.

The TX-OP-028 range is used in all their finished products such as the M3, M5, M6 and M8 pre-amplifiers. There are various options on the TRANS-027 as the range has now expanded to include not only copper (primary winding) / copper (secondary winding) but also copper / Audio Note™ silver and all Audio Note™ silver wired versions. There are also the I/E or double C-core versions with different core materials available too.

All Copper – Copper transformers have copper lead-out wires, Copper – Silver have copper on the primary and Audio Note silver lead-out wires on the secondary and silver naturally silver all round.

The TX-OP-011 which has the same options as the TX-OP-028 is a pre-amplifier output transformer that can be used pretty much anywhere and is especially used in simple line pre-amplifier circuits like the M1 and M2.

All the above pre-amplifier output transformers are the same size, whereby copper frames come as standard, 78mm wide by 67mm high by 67mm deep, with mounting holes centre to centre at 54mm by 54 mm both with transformer standing up or lying down.
