LN106 Phono Preamp
Precise RIAA correction. 8Hz subsonic filter. MM 40dB gain Low noise: 82 dB SNR. Small size. The LN106 solid state phono preamp provides precision amplification and RIAA correction for MM cartridges. Standard input load is 47K and 120pF; others are available. A 8Hz subsonic filter suppresses all frequencies below 8 Hz while keeping the in band sound signals unaffected. The subsonic filter greatly reduces unwanted cone movements due to record warp, etc. Power is provided using a 24VDC wall adapter. This is a cost effective way to provide power while eliminating powerline hum. We use the highest quality op-amps, 1% metal film resistors and 2% polypropylene capacitors for superior sound. The LN106 can be used "stand alone" or can be built into the base of the turntable or into existing preamps. Connectors: Inputs: Output: Grounding: Power:

LN108 Tube Phono Preamp Precise RIAA correction. 8Hz subsonic filter. MM 40dB gain Low noise: 81dB SNR. Small size.
The LN108 solid state phono preamp provides precision amplification and RIAA correction for MM cartridges. Standard input load is 47K and 120pF; others are available. A 8Hz subsonic filter suppresses all frequencies below 8 Hz while keeping the in band sound signals unaffected. The subsonic filter greatly reducOptional DIN connectors instead of RCAes unwanted cone movements due to record warp, etc. Power is provided using a 15VDC wall adapter. This is a cost effective way to provide power while eliminating powerline hum. We use the highest quality parts, 1% metal film resistors and 2% polypropylene capacitors for superior sound. The preamp uses 2 12AX7WA dual triode tubes. We normally use Sovtek, but can also supply other brands. Each channel uses two triodes for voltage amplification and one triode as a cathode follower. The RIAA network uses a passive configuration. The power for the filaments is regulated 12VDC, using an internal voltage regulator. A DC/DC converter steps the 12V to 240VDC plate voltage. The LN108 can be used "stand alone" or can be built into the base of the turntable or into existing preamps. Connectors: Inputs: Output: Grounding: Power:
