Roland Space Echo

[Daniel Araya]

Hi!

I have 2 201:s and they both oscillate happily! I have serviced a few of 
them to, and i have found that cleaning the heads carefully and installing 
a fresh tape usually fixes it. As an example an old tape it usually starts 
oscillating at 2 o' clock on the intensity dial but with a new tape and 
clean heads it starts at about 10. I think there might be a trimmer on the 
pc-board that also affects the feedback.

I would really like to se the schemo for this one.

I have made replacement tapes out of standard reel-to-reel tape, with a 
diagonal splice and have seen several different lengths of tape, ranging 
from ca 300 cm to over 500.


If your machine still fails to feedback properly you might try another, 
newly made tape in case your replacement tape is bad. Also check the wiring 
to the heads and maybe the head alignment. And check the intensity 
potentiometer to.


good luck!
