help! no sound

Hi Audiogoners-

I am just hooking my stereo up after several months of inactivity during a renovation project.    I run a bnc out from my cd player to a Schiit bifrost (using adapter there for bnc).  I have RCA cables to the Lyr 2 amp.  When I play the cd player I get no sound.  (The cd player is producing sound through the speakers.)

This set up worked before and I am mystified.  Any idea what's going on?  Should I sent the LYR 2 back to Schiit for a repair?  Or is this user error?

Thanks for any insight!

Margot

If none of the above works it's possible your BNC adapter is bad? At least that would be cheaper outcome.

Hi all!

Thanks for the help.  I think I have done all of these things.  Spoke to Schiit and they think the tubes may be bad.  (Seems weird that would lead to NO SOUND rather than hissing) but I'll get some new tubes and see if that works.

Thank you!

Before you had music. But now…you ain’t got Schiit. 
Sorry couldn’t resist.

@mcanaday -- "Seems weird that would lead to NO SOUND rather than hissing"

Hissing usually happens due to a tube's age as it approachs the end of its useful power-on lifespan. That can range from 1,500 or 2,000 hours for a power output tube to many multiples of those figures for tubes used in preamp stages.

Obviously, a tube can fail in other ways, sometimes quickly, that completely interrupts the circuit.  Sounds like this may be your situation.

Hope you find the replacement tube fixes your problem.

Hello mcanaday!  Cables are the least reliable things in most sustems. Particularly the ones with phono (RCA) plugs used in most interconnects. You mention you were putting a system back together. Just this evening I was putting a system back into operation following a flood and I found two cables that were intermittant and had to be wigged jusst right to get the signal thru. I have lots of cables and replaced them. I am a very careful guy and these were from a reputable company. But they do suffer from a lot of pulling and pushing and go bad somtimes. Check them first. Good luck!
