Binson Echorec - Click HERE for Original Thread
ramalamafafafa
Has anyone built a binson echorec 2?. The schematics look realy quite difficult? Anyone have an experience building/owning one..............ohhh, for anyone who was curious, the echorec 2 is tube-echo unit built in the sixties.

I would have thought the electronics would be crude and simple (like all valve stuff), it's the mechanics that are likely to be the difficult part.

Hmmmmm, i would think the mechanics are the easy part! Im somewhat of a beginner in electronics, so it all looks kinda complicated and difficult!

Why do you wish to try and built such an antique anyway?, things have moved on a lot since then :D

So what particular problems are you having, or anticipating?.

Im basicly thinking it will be a mind numbing task to follow a schematic that large (its all sorta large to me, as ive not been into electronics for very long!!!). I realy love the sound of those old echo units......................they've long since become outmoded and obsolete, but they have a strange sound quality to them that i dig. (it could be described as "fantasticly lo-fi and crappy!"). This particular unit has a number of sounds and features i like....Anyone who has ever watched and enjoyed an early pink floyd vid knows what im talkin' 'bout!

I suspect that the sound you like isn't so much this particular unit, but the quality and skills of Pink Floyd :D

Like I said before though, the electronics looks pretty simple, just a collection of triodes - but the mechanical part is likely to be tricky, and probably requires special transformers to interface to as well.

Yes and no. Ive also heard rather terrible guitarists play through it and i still loved its tone....i have a schematic, im just a little bit...............................overwhelmed???? (i can read em, just.............)

Hmmmmmmmmmmmmm, i think the mechanical part is basicly a motor running from the transformer, fairly simple i would think. You are right, the electronics are realy just a number of triodes (six to be exact).

How would that give echo?, you need to record the audio, and play it back after a delay - from the Binson website

Binsons were unique in their construction, utilising a specially designed steel/alloy disc drum, which carried a durable flat metal 'tape'. The life of these drums are 40 years plus at the time of writing. The drum was driven by a powerful AC motor, in most cases, via a rubber jockey wheel, which kept the transport very stable. Record and playback heads were arranged around the drum periphery, the longest delay, or playback echo being a nominal 350 - 375 milliseconds.

Well yes, the motor spins a metal disc which has a number of playback haeds, a record head, and a erase head. As the disc spins, the signal is recorded to the disc, then played back via the playback heads. It is essentialy a tape player, like all tape/disc echos. Probably should have added that "minor" detail!
