Tape Project Machines / Technics RS-1500US servo issues newbie post
« on: July 14, 2008, 11:48:30 PM »
First the good news. I WAS going to modify one of my older Ampex 350 series or Otari MX-5050 4channel machine (not 1/4 track) with another head block, or one of my other decks to be used with my Seduction kit for Tape Project tapes.
I already have 2 tapes so I am anxious to get something going !
Today I became the owner of a well used,  partially non-working Technics RS-1500. One of the toggle knobs on the right is missing and the deck is dirty but otherwise not that horrible. The heads look OK and it is, being a 1500 1/2 track play/record  with 1/4 track play. In initial testing, it powers up and fast forward and rewind work, but play does not. The pinch rollers engage and it starts to move then slows to a stop and then goes back into stop mode. So my guess is capstain motor and servo mechanism. Anybody know where to start with this particular malfunction? Otherwise it looks like it might work OK ! A related question is the idler which the tape wraps around at the bottom seems to have an inner and outer ring with 2 little dots on them that turn separately, then the flat spanner nut in the middle. What is that all about? I guess because of the red LED on the outer edge that this is part of the speed strobe sevo mechanism.
In any case, because the former owner was frustrated and the deck was not pristine by any means, I was able to pick it up for almost nothing. So I have some refurbishing room even within my limited budget.
Hope I am not going over material previously covered. I did try to look for this problem elswhere on the forum.
Thanks - Steve
