Mastersound 845, as described in the quote below (lifted off the net):
The Italian designed Mastersound 845 Reference stereo integrated amplifier uses parallel Billington Gold 845 triode tubes to produce 40 watts per channel. New old stock (NOS) Tung-Sol 5687 blackplate for rectification and NOS Raytheon 7730 for pre-amplification round out the tube compliment. The 7730 is a premium version of the 12AU7 made only by Raytheon as it provides very low noise and heavily plated gold pins. There is zero negative feedback in this design that weighs in at 50 kg.
Escalante Design Fremont speakers and front end was Wadia. Great sound but probably not the best speaker match for the Mastersound.
