Mastersound Dueundici EL34 Single Ended Class A Valve Amplifier
Selling as going pre / power.
This is the non RC version. The Alps pot does have the motor connected to it but it does not have the board (not sure if this can be retrofitted). New retail of the RC version is £2300.
I am the 2nd owner of this amp and it is in excellent condition. When I received it I removed the amp cage but the new owner can add this back on if wanted. So the picture of the amp with the cage is a stock photo (not one I took).
I also wanted the cage off the amp so I could add Pearl Tube Coolers / Dampers as seen in the photos - these will be included (all 4) :)
So this amp has had a few small tweaks.
1) Output tubes are new issue Electro Harmonics from Cryoset in the USA. These have been cryo treated. They have about 80 hours on them.
2) The preamp tubes have also been upgraded to NOS ECC82's made in Yugoslavia on Telefunken tooling. They too have low hours - about 90. So the tube compliment cost a few £££'s.
3) The original Arcotronics coupling caps were removed and upgraded to ClarityCap CSA types as seen in the photos. This improved transparency, dynamics and opened up the top end of the frequency spectrum (more extended).
4) Hifi Tuning Supreme fuse in IEC and HiFi Tuning Silver Star on the audio board.
5) Some Sound Coat inside the chassis to absorb any resonance - can be seen in the photos.
6) What appears to be Japanese writing on the power supply caps is actually Akiko Tuning Chips which can be pealed off if preferred.
Review here but with the cap, fuses and tube upgrades, expect a more lively amp: http://www.6moons.com/audioreviews/mastersound4/1.html
