This is a tube preamplifier for record players with MM cartridges.
The dual mono topology ensures a better listening experience.
The RIAA network makes all frequencies come clear and in a good balance.
The preamp design mostly comes from a known Australian hifi proffesor (thx).
Contains four new 6N2P tubes ( direct replacement for 12AX7 type tubes ).
Pretty nice sounding preamp.
You can plug it directly into a power amplifier.
Works on 115V / 230Volts ( US and EU standards ).
Shematic included.
