So the time is coming to stick it all together, still a while yet but the majority of parts have arrived.
First the Cornet Mk2 -
Essentialy the same as the first Cornet, but with a few changes. The CCS is now on the board and not a lash together as before. More space on the board aswell.
The large alluminium can type caps are 51UF polyprop in oil, these are to replace the electrolytics for B+ bypass.
Elna Cerafines, 10,000UF for the heater supply. Signal coupling will be TRT Dynamicaps with Mcap for decoupling.
resistors in the IRIAA stage are Kiwame, Mills non-inductive wire wound for the power side of things.
CCS caps are blackgate.
Copper chassis was sourced from Ebay US. Very well made from 1.5mm copper with copper welded seams.
Valves are Mullard NOS ECC82/83 in the amplification. B+ rectification is a Mazda 5Y3GB.
I suspect a liberal sprinkling of ERS will be used between power and signal sections of the board.
The TT -
Platter is an 80mm think Scheu (Germany) item, with inverted bearing from the same source.
Motor is also supplied by Scheu, a DC PLL controled item.
Plinth is a circular piece of slate. 250mm diameter and 55mm thick (looking for a coating/wax suitable to give a deep finish)
The arm will sit ontop of its own stand. Stand will be made from solid brass with adjustable spike feet.
Cones for the plinth will be brass again.
Motor will be housed in a circular alluminium box. The motor box will be standing on a seperate shelf
The arm will be an RB300 with mods -
Michelle Tecno weight
Incognito rewire.
VTA adjuster isn't decided yet, but the OL sliding one is looking favourite.
Cart is a DV 10X5.
Support for the TT is a wall shelf, i will probably try to borrow a pnuematic support of some kind to try with it. If i like the result i will be sourcing one to use.
Will probably try a weight aswell, but not finalised a design.
So, there ya go, its finally coming together.
Comments good and bad welcome 🙂

An externally hosted image should be here but it was not working when we last tested it.
