Wheatstone SP5 SP5a Channel Strip Mic Preamp w/ Input Transformer Audio Arts. I use a SP5 Daily and I have accumulated 50 or so Extra channel strips. This listing is for a Mic channel I don't have many of these. It uses better coil and transformer input transformer. After the transformer the microphone amplifier goes through a 5534 for operation amplifier.
This is a very clean and neutral sounding microphone preamp. After the Preamp there is an insert for more processing.
Directly after the insert is a three band semi parametric Equalizer. On the high band it uses a poly styrene capacitor. The XLR input jacks in output jacks are swiss made Neuitrik. The channel strip I have photo is missing a couple operation amplifiers.
This channel is tested and I did not see any issues with it before storing it. Also I have the complete schematics for this console I can take a picture of them and send it to you if interested.
The fader has been removed and can be replaced with any 10K 100 mm Fader. Needs +/- 17 volts and 48v power supply.
