Seelmerdave your experience with cap charged for 6 months is really interesting. What CD player is it? Maybe I can find a schematic, curious to look at the circuit.
One of my first jobs was TV repair, back when they were almost all tube. We did discharge caps then, but it was a matter of efficiency, find the problem and replace the component as quickly as possible. Since then tube equipment updating/repair has been a hobby, I do check B+, before touching, but haven't come across anything that didn't bleed down. But thinking back, the only tube CD players I have worked on were Cal labs and Carver. What I do recall is that the tube part had their own power supply and the circuits were very simple, which would increase the chance of no bleed down path.
