LCR phono tube preamp with 6Dj8 x4. This is prototype version. 6V6 tube was used for regulator voltage to power supply. There is no volume control.

THIS IS PROTOTYPE SALE. If you see the status of this amp is sold out. Price for this set will be 2500USD.

Because it is prototype version so some parts is limit and not available because out of stock. For example the two big oil condenser in power supply.

LCR does not like CR type or NFB type, instead of using CR combination, it uses inductor to equalizer RIAA curve. That makes signal loss much less than using CR for equalizer. The musical of sound is much better than any other type of equalizer. The disadvantage of LCR amp is the impedance of LCR block is very small and it make design of phono stage is very difficult.

Power supply use 6V6 and 6DJ8 for voltage regulator.

Specification:

Response frequency: 20Hz ~ 20KHz
Hum level : -90db
Input: 100V, can be changed to 117V or 230V

There is no volume control in LCR block. Your power amp need volume control or your need to use preamp.

This is prototype version of LCR phono block that takes me years to develop. It is result of experience and many feedback from customers
