    I know you said "non-negotiable"........ However.............

    FWIW, I am offering £200 for the amp boards and the transformers.

    Did you break the transformers down yourself? Can you confirm you've drawn current through them and they're non-hummers?

    My electricity supply here is awful and averages 248v which has given me hum problems in the past with inferior mains transformers.

    These two transformers came to me in two NAP110 amplifiers that I bought earlier this year from a friend and fellow fish. One of the amplifiers had been through my hands previously for service. I initially converted them to a pair of 110 mono amplifiers fitting them with Avondale 110 power supply modules and selling one of the pairs of NAPA boards. I then had the opportunity of building one of the first pairs of Avondale QUDOS (NCC220) amplifier boards which I fitted in place of the Naim NAPA 5/4 boards. Knowing, from previous experience, that Avondale amplifier boards benefit from higher voltage rails than those present in the NAP110s I specified some new transformers from Canterbury Windings which I fitted in place of the H & F ones that I'm now selling. Some of the history of this project can be seen in these threads:



    Yes, I removed the transformers from the 110s myself.
    Yes, before removing them in October the transformers were in almost daily use by myself for most of this year.
    Yes, I can confirm that, whilst I have had them I have had no problems with hum.

    Thanks for your interest.
