Hi,

Does anyone have a schematic for the Solid State Binson Echorec 2? Same as the Guild and Sound City Echomasters.

I picked one up the other day. It works, however the repeats die away quite quickly and aren't really loud either. I've taken it apart and begun the rewiring process, however I have noticed 1 transistor that looks very different to the rest.

The majority are BC208B however there is one that looks to have been replaced and looks out of place and is BC239, along with a pair of resistors that do not look original.

If there are any Binson experts here, I can send photographs

Cheers in advance
Phil R

Hi Phil ,
Im a bit of a Binson fan , I have an echorec 2 tube . I did renovate alot of the wireing and bad caps years ago ,but some of the crud wire remained until it further disintegrated and now its unusable . I will fix it up one of these days alright .

I did find this guys site ,

He's got some great info on Binson stuff here too ,but I cant see any solid state Binson schems.
Maybe an email to Effectrode might be worth while ,he's bound to be able to point you in the right direction .

Hi guys,
I've been trying to find the schematic for this as well.
I have one with rotten cables and caps that crumbles when touched, not sure if I dare to work on it without the schematics.

I've been there , years back I got my old tube Binson going long before there were such things as online schematics available .
I recall having to replace quite a few resistors , particularly anode load ,that had drifed way way out .
I guess taking detailed hi res photos before touching any of the fosilised wiring is a good plan , not that the schematic wouldnt have helped me , but things such as wiring dress, layout and placement isnt contained in the schem anyway , so good to at least have some reference points to work off . My method was just replace one wire at a time , before moving on , even if the insulation is gone , you still have the means to trace where a wire starts and finishes with the meter , make a diagram and note on paper so when the wire turns to dust after you touch it you still know what connects to what .

A labour of love , thats what I'd call it .
