A black hole went into my Marantz SA-10!


I always use a Herbies black hole II CD disc damper. It somehow got lost inside the transport. The tray is shallow as is, so it didn't take much for it to get knocked, and in it went! So I freaked out. I looked inside behind the tray with a bright LED flashlight. I didn't see it. Everything works. Tray goes in and out without any snagging. No skipping. I'm not not very mechanical and have no idea which screws to loosen and don't want to mess with it. It happened about 30 hours of listening ago. I use the Herbies black hole CD disc damper for 6 years. When I had my Sony 5400 ES it did make a difference and was repeatable. My GF agreed. I never did the AB comparison on the Marantz. Maybe the transport on it is not tweakable since they built it themselves. I know Steve Nugent here is a big believer in some kind of damping. Anyway its playing.

I did call Marantz and I would be voiding the warranty if I put a dampening sheet on the inside top cover. I think it's silly but the rep answered straight up. So I'm thinking just put it on top. It won't be out of the way but it should serve the same purpose. I can add and take away as needed.
Damping externally for the top is probably an ok idea. I would never consider placing damping material, which is a great thermal insulator, over a transformer which can get hot.  Insulating the case too much may prevent heat disapation required by the designers, and heat is the destroyer of electronic components like capacitors.

Can anyone tell me what the output voltage is for this player when using balanced connections?
