Moving coil pickups do not provide very much signal! From an objective point of view, valves/tubes are not an obvious choice of electronics for this job. MC pickups are low impedance devices, delivering so to say more current than voltage. Since tubes are high impedance devices and can be noisy, - there are many problems to be solved. Today, I might look for a different solution, maybe a grounded grid, which includes a negative supply, if I was to stay with tubes..........
Anyway, the present diagram / amp is my own construction. Since you need maximum gain from the first stage to fight noise, I went for a constant current source as anode resistance. The first version used a depletion mode FET transistor, worked, but high voltage combined with low noise made it difficult to find the proper FET. I tried a number of solutions, including 2SK 389, and used the 8 pin IC socket and a pin mount to check and switch FETs. Later on, I found the bipolar 2SA 737, extremely low noise together with a very low bulk-base resistance, and decided to use it. The diagram is fairly simple, one ECC 88 double triode tube, connected in parallel. Amplifier gain depends on the used tubes, no tubes are exactly identical, but expect something like 25 - 35 X with ECC 88. As I mentioned in the McIntoshLJ preamp section, you will need some sort of gain adjustment later on in the following preamp. You will also need a high impedance input - suggestion is 1 M Ohm. Tubes must be selected in respect to noise. Circuit inverts absolute phase.
When I worked with this amp, I had access to the Ortofon T2000 head amp transformer, which was a very expensive piece of equipment at that time. Several friends came for listening sessions, compairing sound with my amp. General impression was that T2000 was less noisy, but my amp had another freedom of sound, more detailed top and a better soundstage. I was happy for that verdict! The amp is still in use today.

Distortion measurement, LJ Moving coil amplifier
Here, I start with 2 measurements. As you can see, this is from 1993, measured with High Fidelity Magazines Audio Precision instrument. THD and noise, input level is 3 mV. A THD figure of 0.04 precent is quite respectable for a tube amplifier. Another impressive feature is overload limit, you can easily put a 200 mV signal into this amplifier, far beyond any output from a MC pickup.

FFT measurement, 3 mV input. 2 order is dominant, the rest is about -100 dB down.

MC amp cabinet. Standard industrial type, not very charming, but lot's of space and fresh air for the tubes. Mains transformer and rectifying bridge in separate cabinet.

Power/input voltage connector to the left is military, bayonet type,can handle high voltage. Central ground female banana conn. Output and input. Multipole computer connector was used for a period, to parallel input and output connector pins in order to reduce connection resistance. Solid, superlow resistance connections are mandatory with MC pickups.

More power supply / regulation than amplifier??, Maybe. I wanted to minimize any hum and noise, and since my own measuring equipment at that time was limited, I did EVERYTHING I possibly could!! The huge 250 V 6800 uF capacitor is for high voltage supply, the grey 50 V 10 000 uF capacitor is for the heaters. Diagrams for all regulators further down. Note also the metal shielding for the tubes.

Amplifier diagram. Input resistance (here, 47 ohms),should be selected to match the actual pickup. 0.45 V cathode bias ensures huge input margin before overload.
Diagram, High Voltage regulator, LJ Moving coil amplifier
High Voltage regulated supply. 2 stages, one series, with TL 783C IC, next stage a parallel discrete regulator. Note the 1000 Ohms 17 W voltage drop resistor. Regulator IC is OP 77, that controls the shunt transistor. It has it's own Zener Diode regulated supply (Pin 7). Resistor values are not critical, can be adjusted to other working conditions. Some L - C circuits after regulator to reduce noise.
