Here is an overview of this singular analog delay. The EC280 was allegedly the very first bucket brigade device delay around. I don't know about that but it was the first Dynacord released and it paved the way for their futur classic units like VRS 23, SRS 56 or TAM 19 / 21.
What makes this unit special is the use of BBD chipsets to create reverb spaces. The result are totally unatural reverbs but that are extremely deep and beautiful. The sound is dark and dense, and a bit gritty, you wont't get very define repetition out of this echo unit but it really glues the instrument you run into it. It further has a 'chorus" level that acts peculiarly too since you can't set the time of the chorus, it is tied to the delay 'speed'. With this chorus knob, fast speed setting and high feedback level ('regeneration') you almost go to flanger territories.
A very unique device it is."

"This is the rare first non tape delay produced by Dynacord. It uses 8 Philips TDA 1022 bucket brigade device chipsets and offers echo and reverb mode, along with some kind of modulation labelled chorus, very much like the modulation that will be found later on in units like Dynacord VRS23, Yamaha E1010 or Ibanez AD202, here in its simpliest form, the speed of the modulation cannot be set and is tied to the speed of the delay, thus giving some very strange possible effect. The sound is very deep and dark, the reverb mode in particular is magnificient.

The unit was serviced: every single electrolityc capacitors were replaced, everything was cleaned and it is calibrated. It is in fully working order and in very good cosmetic condition, with only minor signs of wear."
