Ok fellas this is the specs on the Micrex R1 valve Preamp
Output Impedance: <2K Ohms
Distortion: <-0.01% (1Vpp)
Frequency Response: 10Hz-100kHz (-3dB)
Hum & Noise: <-86dB unweighted
And this is the spec for the Redgum Audio power amp i have at this time which i wish to mate with the Micrex R1 valve preamp.
RG120ENRm - 155+ 155 Watt/Ch RMS (293 + 293 W RMS - transient)
Harmonic Distortion: less than .009% (below Clipping)
Intermodulation Distortion: less than .005% (below Clipping)
Signal to noise: greater than 100dB
Input Impedance: 10K ohms (matches 600 ohms - 50K ohms)
Slew Rate: greater than 65Volt / microsecond
Damping Factor >800
Frequency Response: 0.8 Hz to 80KHz (-3dB points)
Peak Current: greater than 120 amps.
I have little understanding of how impedence calculations are made and looking at the Micrex R1 preamp and the specs on the Redgum Audio power amp , would they be a synergistic match ?.
any technical minded members able to advise.
