"This is quite a rare tape echo manufactured by Dynacord. It seems to be one of the very last tape echo introduced by the brand (with the Echolette Echo 400).

It shares many parts with the Echocord line of delays like motor, pinch roller, heads, oscillator board etc But this one useS op amps instead of only transistors for amp stages (the Echocord Super 76 also already used one op amp for the output stage).

The unit has 2 heads which you can mix with the dedicated pot. Otherwise classic features like input volume, tone, echo send level, echo feedback and echo level.

In the back the original DIN socket enabled output and aux input. In this case you only get the wet signal out of the delay, which is nice in a studio environment.

Unit was fully serviced and modded. [mods below]

I demoed it with 3 different instruments so you get a good idea of how it sounds with different sources. First is a Roland MC-202, analog mono synth, then an analog drum machine (Roland CR-78) and last an electric guitar (Squier Jagmaster, not in frame). Please note the SE-251 has no hi input impedance so I run the guitar through a DI Box first.
