MY pioneer RT-1050 is going in to be serviced due to a failed channel and some other trivial issues. While it's at the repair bench, what should I tell the tech to do? I want the thing quieter... not that I've noticed it being noisy, but I really want to know the output path has been gone through to be as quiet as it can. That means new resisters, new caps...etc. Can a competent tech creatively take a look at this? I mean it could be two resisters in an audio circuit that make more of a dramatic change than an entire re-cap could. So I'd like to get this machine from 1974 to get souped up for low-noise recording as the music I tend to tape is very dynamic. Any thoughts on what to ask and how much to expect to pay? Thanks! JOhn
