Roland Space Echo

[Nick Thompson]

Hi,

I hope this is not too off topic.  I have a Roland space echo that is not
functional.  Mechanically it seems fine (the tape moves across the heads,
the speed control slows and speeds it up).  The reverb part is fine too.
The problem here is that sound just builds up into a cacophonous wail.

I really want to get it working again, is there anyone here here who can
work on it and diagnose and fix it?  I tried my local (and usually really
great) tech, at musicians service center in San Jose, and he diagnosed a bad
erase head.  He said Roland were out of parts, so he would not be able to
work on it.  This guy is a usually a great tech - he's bought many an old
piece of junk back to life.

So what I'm looking for is a tech somewhere who has some experience working
with tape delays, to attempt to diagnose the problem and (hopefully) fix it.
I know there are several service people on the list, and there maybe a DIY
person who knows a lot about these.

If you can email me that would be wonderful.  I don't really want to do this
as a diy project myself because I'd really like to have a good chance of
making this work again :)  And I can just about do solid state electronics,
all of the mechanical elements of this are probably beyond me, as are tape
machines.

Many thanks!!

Nick
