Help with a BAT pre - amp


I just took delivery of a VK 50SE and found once installed I am getting a loud pop sound once in mute or zero volume is engaged.

A respond from a BAT user would be appreicated.

Did you get an unbeatable deal on the 50SE that can't be passed up? If not, here's what I'd say. Unlike the others my thought is, you just took delivery on a used preamp and you're immediately having a problem with a "loud" pop. You should contact the designer to see what he says. The seller was fair enough to say you can send it back if you're not happy. I would take him up on that offer after I hear from Victor unless the problem can be resolved without shipping the preamp. . At this point are you happy? Plenty of BAT preamps show up here regularly including the 50SE. You can get yourself another and not have to deal with an issue right out of the box. I sure wouldn't want to have to be hearing loud pops, posting for help, emailing the designer, facing the possiblity of having to ship the preamp for retubing, and trying to troubleshoot on a preamp I just bought. Now if it just needs a re-tube and the designer says, "sounds like tubes" and you don't mind having to ship the preamp, and wait for it, then ok. Me, I woudn't be shipping a preamp I just took delivery on unless it was back to the seller. Now, if the tubes were exposed and a simple process to get replacements and re-tube, that would be a bit of a different story. If your popping problem is tubes and you can do the re-tube yourself with BAT supplied tubes fairly simply that would be a different story too. But at minimum it sounds like you face shipping the preamp to BAT, unacceptable.
Did try to reseat the tubes or at least rock back and forth? Maybe one came lose in shipping.
Thank you gentlemen I took the opportunity to rely on my sources. Victor for one told me this morning that it is the output capacitor that leaks and goes dry (six-pak) and the fee to fix was 900.00.

I appreciate what Foster 9 mentions and he is correct due to the fact right out of the shipping box there is a problem raises a red flag!

Seller has arranged for me to ship unit back.

Thank you again to all my Audiogon fellow members for your feedback on issue.
