Two box MM and MC switchable unit that was Mr Firebottle's personal BB3 as good as it gets (his words not mine...) This version includes a power up mute circuit that silences the output while the valves stabilise.
Two INTER PCC88, Seimens valves branded for Inter plus a rare Marconi ECC83. £775.00 plus postage for what could be the best of the breed.
The sticker on the power supply can be removed... Had it a couple of years and it has been stellar... Alas, monies needed for another project so making do with the Nagra.
MC input impedance is 180 ohm with 68dB gain
MM input impedance is 47K with 41dB gain
Output impedance is 270 ohm.
