These two circuits have been requested for a violin pickup but could equally well suit a ceramic or crystal pickup.
Ceramic cartridge amplifier.
Home preamplifier and tone preamp stage for ceramic phono cartridge.
Ceramic cartridges of capacitance 800 pf to 12 000 pf with output voltages up to 900 mv can be connected making it a very versatile circuit for a large range of cartridges currently available.
The last ceramic cartridge i had in my system was back in the sixties.
The op amp circuit uses a tl071 connected as a voltage follower.
But the nostalgic type players of today persist in using ceramic cartridges.
Very old tube amplifiers 50 years old have had ceramic cartridge input which is very high input and accepts around 100mv signal level.
The transition from ceramic to magnetic cartridge use generally took place during the 1970 s.
Get it as soon as fri sep 18.
My design concept was to produce a circuit that would be compatible with the widest range of cartridges using the most commonly available and lowest.
Ceramic cartridge phono pre amp.
Vintage audio equipment may need the ceramic cartridge s higher voltage output.

Microwave fuse ceramic fuse cartridge fuse 20 amp 250v slow blow compatible and universal replace for ge wb27x10388 and whirlpool kenmore other microwave 5 pcs.
After plugging a ceramic cartridge turntable into a auz input on a stereo it seems this is correct as the sound is somewhat tinny though the volume.
Mm s will typically be loaded with capacitive loading in the pf range.
I recently obtained two ceramic.
I upgraded this to a moving magnet and this type has been my prefered choice ever since.
Fortunately magnetic cartridges look quite different in that they don t flip over to play 78 s.
The type cartridge between it and my amplifier input which at the time was the high impedance grid circuit iirc of a 6j5 audio triode.
Mm moving magnet cartridges are designed to play into 47k ohms or higher input impedance.
It can run from a battery supply of 9v.
