Over Thanksgiving, I was in NC packing up some of my audio stuff to ship to CA (we're finally selling the NC house). One of the items I shipped was my Sony TA-2000. It was well packed for shipping and couldn't have been damaged, other than from shaking / shock if dropped.
It arrived yesterday, and I decided to see how it worked via headphones. For one thing, neither meter light is working now; they were before shipping. I suppose shaking could easily damage old filaments, but I thought it was odd that both were out. When I turn it on, both output meters read around -2dB initially and then settle at around -7 after a few seconds as shown here:
There is no sound from headphones - no audio from my iPhone connected to any input, no hiss from phono inputs, no staticy controls, etc. When I get it home, I can connect the line outs to an integrated amp to see if the issue is with the headphone amp or elsewhere.
As far as I know, this unit is original. I'd like to do what's necessary to make it functional and safe to use. By that, I'd like to be able to use it without worrying about any damage to other components. I know pots and switches will need to be cleaned, but that wouldn't make the meters read high. I'm looking for feedback as to where I should start here. I'd assume the power supply board would be first, but what's next, and where would I start to correct the meter issue and lack of output? Sony's service manual looks to be really good, with view of component and trace sides of all boards, well-labeled components... I wish all were this thorough. Due to the 'modular' construction, this looks like it could be relatively easy to work on, though there are a ton of components. Below are some pics for fun.
