May 30, 2007 · Here's the circuit The attached has the pre-amp's circuit. Looks like this chip is used in the phono pre-amp section. The post on TVK claims the M5238L chips are mediocre and should be upgraded. I was wondering about eh NJMs too.
Aug 21, 2020 · The active gain stage in the Sequel mk4 is the venerable NE5532 dual-channel Operational-Amplifier, which has ideal noise and input impedance performance to match Moving Magnet amplification requirements. The Link PCB is a small printed circuit board, with 5 pin connector that bridges in the signal from line input 1 to the main pre-amp.
The Flat Preamp can also be used as a cutter head feedback coil amplifier. The Flat Phono preamp may be populated with a wide variety of dual op amps including the bipolar NE5532, NJM2114, NJM2068 and FET input OPA2134. (Assembled PC boards are shipped with NJM2068DD inputs due to their slightly lower noise. Other ICs available upon request.)
The P06 design: The ESP design is a full op amp based circuit, as are most of the ESP designs, but this phono preamp uses a combination of split passive treble EQ and active EQ for the bass end. This combination sounds marvellous. Although the circuit looks deceptively simple, sonically it is superb and I never tire of the sound of my P06's.

Hej, my plan is to use a volumio powered board (am not decided yet) as a controller and digital music streamer for a input selector/mastervolume controlling preamp to feed my dsp amps inside of my speakers. Inputs would be a phono preamp and two aux devices. I see two options: First is to use a simple board like a raspberry b+ with dac as just another analogue source into an all analogue ...
Aug 31, 2011 · The phono preamp shown has an accurate RIAA equalisation curve, is very quiet, and offers far better sonic performance than the vast majority of those seen in magazines and application notes. Like most other ESP projects, it is very tolerant of opamps but the NE5532 dual op-amp is a good choice.
The NE5532 is excellent in this respect, as shown by Self. If this was an integrated amplifier, containing a power amplifier of known characteristics, we probably could omit the the buffer.

This is an update to my previous review of the 540P. While the 540P is an excellent sounding preamp and an amazing value as a stock unit, upgrading the stock output stage opamps significantly improves the sound in all areas. I replaced the stock NE5532 opamps with opamp sockets so that I could try out different chips.
The Sequel 40 MM Phono pre-amp is the standard device which is suitable for most medium output Moving Magnet Phono cartridges. It is a two stage circuit and uses high-grade, NE5532 low-noise, integrated circuits to amplify the signal. The 75us RIAA de-emphasis is performed passively following the first gain stage and is directly coupled without ...

Phono Input Input #1 on the Model 2100 preamplifier is switchable between line, moving magnet, or moving coil cartridges. I'm about the last person you should trust to evaluate a phono stage as I spin vinyl about four times a year (three of those are during the holidays, when I put on old Elvis and Bing Crosby Christmas albums for my in-laws ...
Phono preamplifier schematic RIAA equalization is actually a low pass filter having transition points at frequencies of 2122Hz, 500Hz and 50Hz. Implementing this characteristic is not especially difficult, but is more involved than a simple amplifier. Apart from R1, R2, R3, R4, R5, C3, C4, C5 and C6, all other components implement a stereo filter.
