Vacuum Tube phono preamplifier MC/MM SE-PRE01
product description
Vacuum Tube phono preamplifier MC/MM Sound Experience SE-PRE01
The preamplifier is a high-end dual mono design with MM stage,
using a 6N17B-V military specification vacuum tube. A precision
RIAA filter based on the best components was used: precision
metallized resistors 0.1% and Mundorf Silver / Gold Oil Evo
capacitors. Each one preamplifier channel is powered by a
separate power supply. In addition, isolation transformers have
been used to ensure perfect isolation from mains power supply.
The power supply with super filtration is made using high capacity
Rubycon capacitors.The MC input is available via Lundahl LL1933
Step-Up transformers with two gain stages x8 and x16.The MC and
MM input has adjustable parameters to match the amplifier to
almost any phono cartridge.
The preamplifier consists of two blocks:
- preamplifier block with power supply
- separate transformers unit, connected by a multi-pin Amphenol
connector to preamplifier.
The front of the amplifier has an input selector from the MC and
MM position and Mute for disconnecting the preamplifier from the
phono cartridge. On the back of the amplifier are switches to
match the impedance and capacity to the MC and MM phono cartridges.
