    I am selling a pair of Consonance M800SE Mono Tube Amplifiers

    The most powerful tube power amplifier from Opera Audio.
    Tube amplifiers at a great price from a great company!
    Uses the famous quad matched EL34 of ElectroHarmonix from Russia in each channel, connected in class AB parallel push-pull mode.
    Power output is switchable from 75W in ultra linear mode to 35W in triode mode.
    Fixed bias is used giving external individual adjustment for each EL34 for optimal operating point monitoring.
    Input stage uses a Sovtek 6922 and drivers stage uses two Shuguang 6N8P (6SN7) metal base per channel.
    Carefully selected coupling capacitors and military grade metal film resistors used throughout the circuit.
    Choke and capacitor filtering giving a smooth DC supply.
    A very small global NFB design to optimize the matching with medium to low sensitivity speakers.
    Overall an all rounder with superb flexibility and excellent sound to match with most speakers in the market.
    Control Functions: Power On/Off
    Inputs: Left, Right


    Specifications:
    Load Impedance: 4, 8 ohms. (User selectable.)
    Output Power at 1 kHz for less than 1%THD:
    -75W x2(UL)
    -30W x2(TRIODE)
    Bandwidth at - 3dB: 6Hz to 60kHz
    Input Sensitivity for Rated Output: 600mv
    Signal / noise: 90dB
    Input interfaces: 1 group (RCA)
    Input Impedance: 100k
    Consumption: 90W x2
    Tubes: EL34x8, 6SN7x 4, 6922x2
    Dimension: 446(L) x 264(W) x 155 (H)mm x2

    These are both in excellent (like new) condition, and include replacement tubes.
    MSRP is $2800.00
    I'm asking $1700.00 for the pair + shipping.
    I will also take trades of up to $700 worth.
    My wants are a 2/3/5 channel power amp (Adcom, etc).
