This sale is for Jos Vaneijndhoven attenuator which was sold as a diy kit and later went commercial. It's a relay based attenuator with input selector, both which can be remotely controlled. The manual can be found here.
Because I wanted to be sure that both channels measured absolutely the same, I've ordered 10 additional RN60 Dale resistors of each value (120 total) in order to match exactly the values with my Fluke meter so I'd have identical channel volume. I'm offering these resistors too with the attenuator (most of them are there, about 110 RN60 resistors). I also added a small transformer to power the circuit.
It's of course in full working order.
I'm also offering a chassis for this, as it was used for a small project now cancelled. It's a diy but it's very decent looking. I replaced the used bottom with a new one, so it is like new with the exception of front and rear plates. The rear is been cut for neutrik rca sockets, rca and power. Because of it's weight I'm giving the option to buy the attenuator seperately.
Edit: Attenuator SOLD only chassis left wondering what it's fate will be.

No, it does not need an additional selector switch. It switches inputs (4 in number) by pressing the volume button, the display momentary displays the input number for few seconds before switches back to volume indicator.

I forgot to mention that this controller has a very good feature to go on standby mode (indicated by a dot, see photo 1) in which it consumer less than 1 watt and can be used as a trigger to remotely power on/off the preamp or another device. It is done via an power output which controls a relay functioning as trigger / switch. I'm using the same relay is mentioned in the user guide manual
I'm providing this relay with a fuse in a separate pcb (see photo 2)
I personally used it to remotely power on/off the preamp.
