Here some photos of two versions of phono preamplifiers with the D3a and 600 Ohm LCR RIAA.
Both share the exact same circuit and parts, except one is for MM cartridges or MC with external MC step up transformer while the other has a built in silver MC setp up (LL1933Ag). The one on the left is in the classic 'landscape' chassis style.
The color of the handles still to be decided between black or silver.
The other one is built in the 'portrait' chassis style.
XLR and RCA inputs.
The portrait version will be on demo at the High End in Munich.
