Ceramic cartridge preamp circuit the revitalizer.
Ceramic cartridge preamp circuit.
2 using an fet.
Similarly violin pick ups made by fishman barcus berry and others are piezo devices.
Simple preamplifier circuit duration.
These two circuits have been requested for a violin pickup but could equally well suit a ceramic or crystal pickup.
Buffering low output mm moving magnet pickups.
A level of about 0 1 volt should be fine for those.
The third diagram for a ceramic cartridge which is transistorized i copied it from our stereo radiowealth clair de lune.
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.
In this ceramic cartridge preamp circuit we are able to set the precise equalization required for any cartridge by calculating the required value of r1 from the cartridge capacitance.
As shown above the circuit is actually designed for crystal microphones or ceramic cartridges.
Riaa and buffer preamp for vinyl record players versatile preamp for mm pickups and ceramic crystal pickups.
These inputs have no riaa eq ceramic pickups are amplitude sensitive and the riaa curve produces very roughly a constant amplitude cut.
This ceramic cartridge preamplifier circuit requires the least number of components and produces highest quality sound with wonderful bass.
I would therefore conclude that unless the line input of an amplifier is of high impedance then when using a ceramic cartridge into this line input my phono pre amp will be of benefit.

It can run from a battery supply of 9v.
Dc negative feedback keeps the operating level stable.
The op amp circuit uses a tl071 connected as a voltage follower.
The independent 1 5 v preamplifier circuit explained below is made up of individual amplifying transistor preceding an emitter follower.
I felt it was better to do it this way as it does not require an oscilloscope and specialized equipment.
