Split Phono Amplifier LP Phono MM Moving Magnet Phono Amplifier 

      This is a split phono amplifier LP phono MM moving magnet phono phono amplifier that is worth listening to. The line comes from the classic British old man Graham Slee phono amplifier circuit. Back then, this one was famous for its excellent sound detail and vividness, but his simple line can make such a beautiful sound, so that everyone is impressed by the design skills of the British old man Graham, which can be called a representative in history. design.

LG191B  A split phono amplifier worth listening to LP phono MM moving magnet phono phono amplifier (British old man Graham Slee phono amplifier circuit) 

Simple is the masterpiece of beauty NE5532 cartridge amplifier board. The board is the front stage of the MM phono amplifier, which needs to be connected to the rear stage amplifier or active speakers.

The usage method is as follows: Phono output of record player--->PHONO MM phono amplifier board (that is, this circuit board)--->AV power amplifier--->Speaker

     This is a split phono amplifier LP phono MM moving magnet phono amplifier that is worth listening to. The line comes from the classic British old man Graham Slee phono amplifier circuit. At that time, this one was famous for its excellent sound detail and vividness, but his simple line can make such a beautiful sound, so that everyone is impressed by the design skills of the British old man Graham, which can be called a representative in history. design.

     What is surprising is this amplifier board, the inconspicuous PHONO amplifier circuit, through which the signal of the vinyl record becomes extremely transparent and full of pleasant atmosphere Beautiful music. At that time, many audio critics believed that the phono amplifier alone was worth the fare, even better than the phono amplifier that was priced at thousands of thousands.

     How simple is this line? He only used a Philips plastic NE5532 to complete the complex RIAA amplification. This is definitely a masterpiece of beauty. At that time, the line corresponding to the MM cartridge was matched with a MM cartridge, and the beautiful sound made how many people jumped into the arms of vinyl!  

     The selection of the value of the RIAA equalization circuit for this line has become a textbook for the phono amplifier, but it has changed, and everyone still thinks the original taste is the best, that is Directly use the first-level OP IC to do all amplification work. It is not surprising that there will be such a result, because this is indeed the shortest and fastest design, which is in full compliance with the design HI FI philosophy of the British old man Graham!

     After installation, I found that this line is really good, with strong low frequency and control, and sweet and delicate sound quality. Quiet background and wide sound field.

     The circuit board is compact and easy to assemble with the pre-stage or amplifier.

If you want to start singing and play, and you want cheap and big friends, it is a worthy choice!

Approximate board size: 80mm x70mm. Double-sided circuit board, Meida S NE5532 ceramic seal dual op amp（Gold-plated 8-pin base assembly）The signal gain is about 38db. Japan “KOA” five-ring high-precision resistors, Japanese ELNA gold prince gold tonic capacitors, nichicon Japan Nikon Audio gold electrolysis, Sanyo high frequency low resistance gold electrolysis, Panasonic gold electrolysis, Japan NEC tantalum capacitor signal cross-connection , Single AC 20V or single DC 24V power supply, on-board 7818 voltage regulator block automatically stabilizes to 18V operating voltage.

Four gold-plated RCA signal input and output, the wiring is unique and very quiet.

This line looks simple. After careful study of the line, I found that it is not simple. There are many unique features and unique sounds.

Feature one; The wiring is special and different from the conventional one, the wiring is very quiet.

Feature two; A NE5532 completes all amplification and RIAA work, with the shortest path, low distortion and fast speed.

Feature three; The signal coupling capacitor uses tantalum capacitor and bias voltage, the distortion is reduced by one to two orders of magnitude, the material is excellent, and the sound quality is outstanding.

Beautiful aluminum alloy case, length 80× width 78× thickness 44MM, drawing process, three-sided stripe groove, one side fine grain drawing, blackening process, rounded corners, there are left and right slots for fixing the circuit board , The front and rear PCB boards of the chassis are fixed.
