No doubt  this is a great way to open this section, a Binson Echorec from the sixtis. An amazing tube echo delay well known by bands like Pink Floyd and Hawkwind.


A good friend and musician saved it from oblivion and decided to bring it back to life. Initially he just wanted to install 1/4'' jacks in substitution of the original inputs&output Geloso sockets. That first idea was pushed down into a list of "must do" after I was told for how long the Echorec was lost in a basement. Opening the Echorec to check its guts was the best way to confirm that it needs a deep restoration and calibration.


 There is some mods and repair wich were not done in the best way. A IEC socket was installed with an awfull chasis work, there is some rewired done with cheap amppliance power cord, hairy solder joints, wires bound together with tape, stripped screws, paint sprinkles....

This Echorec needs to "get in shape". But first the main functional blocks must be checked, restored and find out if they are viable: Power supply, motor and magnetic freewheel&heads. Only afterwards I will be able to take care of electronics.

Initial goals:

Around 15W+15W true tube, line and phono MM/MC inputs, SNR around -90dBV, penthode and ultralinear operation for everybody's taste, microcontrolled power supply, speaker protection, dynamic standby etc.

This is the first idea and starting point for the possible configuration of the Hi-Fi amplifier with phono preamp.

We have a new project, a warm and tasteful Hi-Fi true tube amplifier for a 50m2 listening room. The device must include a phono preamp. After formal proposal and a few client design personalizations I have received the "Set sail!".

We will try to show the development of this special amplifier borned in the crossway of pure tube touch and today's tech.

The Born of an Idea:

A few days ago, Pepe contacted me requesting a proposal for a tube device with which he could enjoy his amazing vinyl collection to a new level. While grounding details, I was able to enjoy a little bite of his collection:  Genesis, ELP, Jethro Tull, King Crimson, Eric Clapton y John Mayall, Miles Davis y Coltrane and of course Neil Young. Among all we took a break with Pink Floyd album Pulse (1995 UK limited edition 25-track 4-LP vinyl box set), an analog recording willing to release all its power through a valve amplifier!
