Pleiades phono preamplifier driving headphones


How would a 2 stage EF183 battery powered with the large anode to grid resistor trick sound as phono preamp? A RIAA filter can be included and if the signal is high enough with 1 more stage studio quality hi Z headphones may be driven.


So it's in fact combining 2 or 3 Pleiades V4 preamps with a Pleiades Electra I, II, or III headphone one electron tube power amp.


The sound should be phenomenal as it may be world's fewer components from phono magnetic cartridge to headphones. All stages in class A battery powered. Noise should be phenomenally low too.


Of course if a crystal cartridge is used just one stage is enough.


On the Dansette Bemuda record player there is just an EL84 from cartridge to speaker!


It seems Mike Oldfiled was listening to one of them when he was a kid as mentioned on he BBC Tubular Bells documentary.
