this old pilot oscillator unit is useless. i got it from an auction with some other treasure and boat anchors.  it’s perfect for a mixer. 8 channels. volume. pan. mute.  the neve b535 board will be the pick up amp. its going to be  very simple. fat & clear. the all transistor neve boards are stunning. i’ll add a control room monitor section and  twin microphone/instrument preamp. quite  the complete juicy front and back end in one beaut box. the two upper photos are of a mock layout and of the new panel ready for clear coating.
