Ceramic Cartridge Preamp Circuit

The op amp circuit uses a tl071 connected as a voltage follower.

Ceramic cartridge preamp circuit.

This ceramic cartridge preamplifier circuit requires the least number of components and produces highest quality sound with wonderful bass. 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. Circuit digest 9 615 views. A level of about 0 1 volt should be fine for those.

If you happen to have an equipment with ceramic cartridge input only then you can t use the circuit described above. As shown above the circuit is actually designed for crystal microphones or ceramic cartridges. My ceramic phono pre amp circuit would therefore correctly match the line input impedance typically 100k of these modern day valve amplifiers. It can run from a battery supply of 9v.

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. The independent 1 5 v preamplifier circuit explained below is made up of individual amplifying transistor preceding an emitter follower. These inputs have no riaa eq ceramic pickups are amplitude sensitive and the riaa curve produces very roughly a constant amplitude cut. Ceramic cartridge preamp circuit the revitalizer.

Riaa and buffer preamp for vinyl record players versatile preamp for mm pickups and ceramic crystal pickups. Similarly violin pick ups made by fishman barcus berry and others are piezo devices. 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. 2 using an fet.

Dc negative feedback keeps the operating level stable. I felt it was better to do it this way as it does not require an oscilloscope and specialized equipment. Buffering low output mm moving magnet pickups. Simple preamplifier circuit duration.
