Hi Ray,
We are ready to go building the new Fet Valve preamp, DAC, and 400R and 600R amplifiers just as soon as we get our production run of new silver faceplates.
Due to a small screwup, they got delayed a month in the metal finishing process. All should be fixed now and we should see them within two weeks I hope.
Otherwise, we have working units, complete and thoroughly tested, of all Fet Valve units, just waiting for new faceplates.
Of course we have been doing lots of 400R and 600R upgrades, keeping the old black and gold cosmetics, with outstanding feedback from our clients.
Thnaks for your interest.
Frank Van Alstine
