Tubes and Hybrids / Laney Vc30 - 112 almost no sound
September 06, 2011, 05:56:50 AM
Hello everybody, I'm pretty new here.
I've a problem with my Laney VC30 - 112, and can't find in any troubleshooting guide the symptoms I'm getting from it.
Hope somebody can help: Power is on, all 7 tubes are normally orangy, but I can get only a very weak, faint distorted sound(like headphones) from the amp, and only if I max the volume knobs. This happens in both clean and drive channels.

What I tried already: plugging the send/return jacks - swapping tubes - checking the power supply voltage - looking for evidence(by sight) of something burnt on the board, or broken joints on the valve tube grids.

Another thing I notice is that when you turn the standby switch on, it's not doing the low frequency sound that usually does(something like 60hz hum) when is working properly.

I didn't change any tubes recently and the amp has always been well kept and didn't see much stress.


Hope somebody can spread some light.
