The phono preamplifier uses:
– low-noise triodes 6Н 16 BV, 6Н 17 of military acceptance with gold-plated grids
– transition capacitors Mundorf Aluminum Oil
– precision resistors Vishay
– high-speed Schottky diodes
– Nichicon Muse capacitors in the cathodes of the lamps
– Hitano electrolytes in the power supply (Hitachi subsidiary)
In addition, the following are installed:
– high-frequency interference filter
– DC component filter in the network
– input signal level regulator Gain (for tuning for heads with different outputs)
– RIAA curve regulator in the low-frequency region and RIAA curve regulator in the high-frequency region.
MC heads with low output are connected via RCA connectors to the input of the Ortofon transformer installed in the phono preamplifier.
MM heads are connected to additional RCA inputs of the phono preamplifier.
You can connect both MC and MM cartridges at the same time (if there are two tonearms on the player or two players). On the front panel there is a switch for operating modes - with MM or MC cartridge.
