Is sound reproduction with only one active device from record cartridge to loudspeaker possible?

At your own risk. Use safety precautions when dealing with voltage.


The Dansette Bermuda record player has as high voltage output piezoelectric cartridge and can directly drive an UL84. Then and output transformer feeds the loudspeaker. When a great quality 45rpm record is played such as a good copy of When I Fall in Love - Nat King Cole, it feels Nat is in the room with you. It is breathtaking.


How about using the excellent PHILiPS AD5046N 800Ω loudspeaker directly in the anode circuit? See Pleiadss amplifiers.


It should be extremely loud due to the efficiency of the speaker. And there may be a risk of damaging it due to the direct current.


So why not reducing the voltage and operating the electron tube at say 47V with a a lower anode current?


The Pleiadss 2N3053 single ended 30mW amplifier with only 6mA collector current gives with this fabulous speaker adequate sound level for many rooms. Not loud but of amazing quality and lot soft either.


Could also an EF183 or UL84 be used at even lower voltage with Pleiades bias?


A reproduction of records signal path of world class quality should be possible with just a cartridge, one electron tube and a high Megohm resistor from anode to ground.


Would it be possible too to connect a 2N3053 with a high resistor in series with base to present the cartridge with a high (Zin) or input impedance or using a single ended JFET power amp?
