Not sure this is still going but I'm a huge Univox Tape Echo fan. I have 2 EC100's and 3 EC80's. 1 EC100 is fully working ( I LOVE IT, especially the playback function). 1 out of 3 EC80's working (barely). The one that works barely I managed to get almost new in the box with 3 tapes (one still shrink wrapped!!!), also came with Factory printed out schematics. I could scan and upload if that's any use to anyone here . The Echo on the 80 is a little faint compared to the 100 (is that normal?). I'd also love to get my other 100 working, any insight on that? Would also love to experiment with getting a longer delay time on both... Where to get parts for that? Experienced in soldering but not with this particular unit... Thanks everyone!
