I tried this thread on the DIY effects board but got no takers. I have a buddy who had taken apart a Dynacord Echocord Super, to paint the chassis. I looked this thing up & found that it's a wildly valuable little echo box. He says it still works. I feel that since it was made in the '60s, it needs a cap job. So it's on the bench & I'm waiting for replacement e'lytics to arrive. I have a couple of misgivings: 1) I don't know the exact model (& it doesn't say on the chassis), which really isn't a big deal, but one likes to know these things. 2) The plug connections are of an old audio type that I don't even know the name of. I suppose I could shoehorn a couple of 1/4" jacks in the 2 instrument-in & 1-out spots, but I don't want to ruin the value of this thing any more than necessary. 3) the original tape is still intact; I prob. ought to change that out but I don't know where to get it. This is a beautiful example of postwar German craftsmanship. Exquisite point-to-point wiring, I can see why it's so highly prized! It's got 5 Telefunken ECC83s! Does anyone here have experience with these tape loop boxes? I'd love to hear about your experience. Thanks.
