Ceramic Cartridge Preamp Circuit

This ceramic cartridge preamplifier circuit requires the least number of components and produces highest quality sound with wonderful bass.

Ceramic cartridge preamp circuit.

These two circuits have been requested for a violin pickup but could equally well suit a ceramic or crystal pickup. It utilises the 2n7000 mosfet transistor with minimal biasing overhead. A level of about 0 1 volt should be fine for those. Buffering low output mm moving magnet pickups.

Dc negative feedback keeps the operating level stable. It can run from a battery supply of 9v. As shown above the circuit is actually designed for crystal microphones or ceramic cartridges. Circuit digest 9 615 views.

Similarly violin pick ups made by fishman barcus berry and others are piezo devices. My ceramic phono pre amp circuit would therefore correctly match the line input impedance typically 100k of these modern day valve amplifiers. Ceramic cartridge preamp circuit the revitalizer. The op amp circuit uses a tl071 connected as a voltage follower.

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. If you happen to have an equipment with ceramic cartridge input only then you can t use the circuit described above. I felt it was better to do it this way as it does not require an oscilloscope and specialized equipment. 2 using an fet.

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 third diagram for a ceramic cartridge which is transistorized i copied it from our stereo radiowealth clair de lune. The independent 1 5 v preamplifier circuit explained below is made up of individual amplifying transistor preceding an emitter follower. Simple preamplifier circuit duration.
