Vintage Synth Repair

hello list,
i received a used re201 today.
sadly, no matter what i tryed, the tape-echos(delays)
are not sounding at all!!
the unit powers-up ok and the spring reverb works anmd
sounds fine, but NOT THE TAPE ECHO!
the tape mechanism works and the tape rolls, but the
delays are not sounding at all!!
any ideas what could be broken inside the machine(and
op-amp? something else?)to cause no tape-echos to
sound at all???
also, another problem: the tape-speed is not constant.
in high-speeds it seems to fluctuate... any ideas
about this? could this be healed with cleanign the
tape mechanism?
i would really apreciate any help, as this would give
my tech some guidelines to work with, in my re201.
many thanks in advance,
best regards,
bakis.
