Ceramic Cartridge Preamp Circuit

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.

Ceramic cartridge preamp circuit.

A level of about 0 1 volt should be fine for those. Circuit digest 9 615 views. My ceramic phono pre amp circuit would therefore correctly match the line input impedance typically 100k of these modern day valve amplifiers. It utilises the 2n7000 mosfet transistor with minimal biasing overhead.

The independent 1 5 v preamplifier circuit explained below is made up of individual amplifying transistor preceding an emitter follower. This ceramic cartridge preamplifier circuit requires the least number of components and produces highest quality sound with wonderful bass. I felt it was better to do it this way as it does not require an oscilloscope and specialized equipment. 2 using an fet.

Simple preamplifier circuit duration. 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. Dc negative feedback keeps the operating level stable. Ceramic cartridge preamp circuit the revitalizer.

The third diagram for a ceramic cartridge which is transistorized i copied it from our stereo radiowealth clair de lune. These two circuits have been requested for a violin pickup but could equally well suit a ceramic or crystal pickup. Similarly violin pick ups made by fishman barcus berry and others are piezo devices. Buffering low output mm moving magnet pickups.

If you happen to have an equipment with ceramic cartridge input only then you can t use the circuit described above. These inputs have no riaa eq ceramic pickups are amplitude sensitive and the riaa curve produces very roughly a constant amplitude cut. 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.
