thanks again Dave,update on 424mkIII
wow....big bummer this is getting really crazy. we (teac techs) seem to think the problem now HAS to be the power transformer.This was the "record skipping" sound Im getting on any tape, new, recorded,etc. First they soldered a couple of rca jax, did zip....then they were sure it must have been the capstan motor, replaced that.(just got it back). they road tested it for a few days...no noise, so they shipped it back. Now they were not using my power transformer at Teac. No noise whatsoever. I got it back let it establish its karma in my studio, plugged it up....sounds balls to the walls...crystal clean...i was all smiles. But it did this last time. So when I shut it down and turn it back on a few hours later...ITS BACK....(the noise) seems when the power transormer gets warmed up, thats when the noise starts. even had teac call me and held my phone up so they could hear it, no ? about the noise. I thought maybe it was doing what an amp will do when its on the same circiut like a cell phone, or dryer or something. my studio is on its own circuit. took it to a neighbors house, same thing. so we are convinced it has to be the transformer.teacs shipping me a new one Monday, and Im confident it will be cool. If not, you can watch my psychotic breakdown on CNN, or FOX as I will jump off the nearst high bridge. never seen the Golden Gate, maybe I will fly to Cally and jump off it.
I will keep ya posted.
