connex 4300-300

On the newer EPT0SSB50C echo/reverb board, changing R30 (10K) +/- ohms effects DEPTH of this time based device. It took a 2.7K ohm as R30 to make effect DRY with control just turned on. This unit now behaves as it should.

I realize this is an ancient thread but it's still relevent.

Want to give a shout out to Strykerradio....BIG THANKS for posting this specific info.

Thank you

What radio specifically are you referring to? I actually remember the 4300-300 as I owned one but hated the echo myself. It had the echo board with the potentiometer built onto it if I remember correctly. I don't remember other radios having that board but I may be wrong so as to why I ask what radio you're working on.

Connex 4600 Turbo. All the components on the echo/reverb board I speak of are surface mount technology except this R30 and a couple of electrolytic capacitors on other side of board. See attached pic. Hope this helps.

Thats good to know, thanks for sharing that for those of us that might run into that sometime. That isn't the same echo pcb that was in the 4300-300. It was also smt but much smaller and built onto the back side of the dual control pot. Was not a good sounding echo. I remember it gave that banjo effect as the first poster called it.
