Greetings folks,
I bought a Pioneer CT-F700 on eBay from a local seller. It is not completely working, so only cost me $20. But hey... 3 VU meters!!
As a first iteration, I'm thinking it would be pretty cool to house a Khadas DAC & JDS Atom. A future improvement would be to add a Hypex amp -- it's huge inside there.
I can tell someone has been in there before trying to fix it, but they appear to have been a hack:
* stripped one of the screws holding the faceplate
* re-attached faceplate off-center
* output adjustment pot is slightly loose
* right VU is slightly loose
There are a couple things I want to determine before making a decision on how to proceed.
1. Adjusting the input pot will sometimes pop and crackle and peg the VU meters. Internal oxidation? Is there a typical way for dealing with that?
2. The outer knob on the input/output pots comes off, but the inner knob does not. Also, instead of the inner and outer being separately adjustable for L & R channels, they are fixed together somehow. Has anyone seen something like this? Seems like whomever hacked on it previously did something here for some reason. I haven't tried prying on the inner knob yet as I don't want to break anything. It is weird and the two things together have me wondering if there's something going on. You don't suppose someone glued it up do you?
3. The left channel output VU works fine, but right channel VU never moves. The right channel is passing sound properly to the headphone, so need to track down where the failure is. (That the right VU happens to be the loose one makes me suspicious someone tried working on it already.)
Any advice, including web sites for this kind of thing, graciously appreciated. Thank you.
