Im planning to build the esp project 88, as my first complete DIY audio project. Constructing this design shouldn't be a big problem, but if anyone has suggestions, please let me know.
I want to use an relais source select for my inputs, instead of an rotary switch, but I can't find any schematics.
Maybe someone can help me out.
 
Let's see,

To start with, I need the following inputs:

1 cd
1 pc
1 tv
1 tuner

later I will add a phono input and a aux input.

So that makes 6 inputs to switch between.

Les, you from Avondale also make Quad 405 upgrades, don't you?
Maybe you can provide me with some information?
 
switching inputs by relays

If you can do with four inputs (= four relays) you can control them by wiring 2 double throw toggle switches on the front panel.

i.e. four combinations

00
01
10
11

Each combination switches on a different relay.

The relays can be mounted on matrix board near the input sockets.

This is what I put on my own preamp.

If that is the sort of thing you are thinking of, I can do you a more detailed diagram.
