I bought one of these yesterday and am quite happy with the delay sound, It has 3x V3205 BBD's and I would guess from the way the switch for standard and long delay works that, in the standard (S)short mode one of the V3205 chips is used with a lower clock freq while the longer delay (C) either 2 or all 3 BBD's are used with a higher clock which would give the long but clearer echo. Just guessing at this stage as when switching while playing I can hear that the long delay makes the sound pitch up.

anyway I took a picture of the top of the PCB to show most of the gubbins.

3 x Coolaudio V3205 BBD's
1 x V3102 Clock chip
! x Sa%&! compander
and The last IC is a 4558d dual op amp.

It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

Still like the table they use for binary datecoding :D

If there is anything you want clearer pics of Dirk I can take them, I haven't done a picture of the bottom yet but is easy enough done. It doesn't look too difficult to trace but will be tiresome on the eyes. I will get some better pictures tomorrow.
