Complete RIAA preamp in dual mono design, all hard-wired, external transformers for each channel.
The design is based on the famous OP-amp LT1028 from Linear Technology used by Mark Levinsson and many other.
Capacitors from Rifa, Evox and Elna.
The solid box is made of aluminium and contains a blue (of course) LED,
the brightness of the LED is adjustable via a potentiometer (in order
not to disturb since the RIAA preamp is intended to be switched ON continously).
The rear contains very fine golden teflon isolated RCA connectors plus inputs for the two power supplies.
New model with a better case will come later this year!
