Calling BAT amp/preamp owner


Hello,
First of all, my set up is vk75se, vk50se, krell kav300cd, and sf grand piano. I just notice yesterday (I didn't really pay attention to this before) that my system produces quite loud popping noise(static?) from speakers when I mute or turn the volume to zero. I am wondering if my fella bat owners experience this too. I tried to pin point the problem but got some mixed results. First, I suspected a bad driver tube, because the popping noise appears on the same side as the bad tube is (I swapped tubes left to right vice versa), but when I use my Krell HTS preamp, this popping noise is not there when I mute/turn down vol to zero. Which mean the driver tube is ok. I'm confuse...

It is probably from your vk50se. Mine have the same popping noise from both channels but they are not loud. I talked to Victor at BAT about that and he told me it is normal to have a little noise when changing inputs or turning the volume. But if the noise gets louder over time than I should send it in for him to take a look.

I am not sure it is the tubes. I suggest you discuss it with Victor. Victor is great to deal with. he will answer every question you send in.
Heeengky,

Thanks for sharing your results. It looks like I should retube my vk50se. How does the sovek tube sound compare to the NOS from BAT?
