DC Leakage and dealer issues

I was auditioning an amp from a well known Canadian designer. The amp played for 30 seconds and then blew. The designer told me that my preamp must have DC leakage and that the amp has DC protection circiuts. The Spectron Digital amp I also auditioned also kept turning off but did not blow. The other amps I auditioned Pass X-250, Rowland M-112, Plinius 102 and Sonogy Black Knight II, etc., did not have any issues with my BAT preamp. I took my BAT VK-30SE preamp to a dealer who told me he could not find the DC leakage. I wrote to BAT and they told me to measure the output with a volt meter and when I did, I did not get a reading. I returned the amp and received a second amp to audition. BTW, the manufacturer also wanted me to become a NY area dealer if I wanted to accept their offer. The second amp keeps turning off after 5-10 minutes of play, again they are telling me DC leakage. I have advised them that I do not want the amp and that I am sending it back for a full refund. The manufacturer now wants me to pay $400 repair costs for the first amp that blew up plus their customs fees. That would mean that it will cost me $830 (including my shipping and customs fees) to audition a $2200 amp. Boy am I pissed off.

What do you think I should do? I still have to ship the second amp back.

All comments welcome.

Did you have the Canadian amp set to French or English when it blew? (just kidding.)

Peter, why not refer the manufacturer to this thread, and then see if they want to continue in their present vein? In the retail businesses I've been in, we have a saying: An unsatisfied customer will tell a hundred times more people about their experience than will a satisfied customer. If you sell somebody a great widget that works as expected or even better, they might tell one person; if you sell them a bad widget, and particularly if you then give them a run-around about it, they will tell a hundred. In the case of the internet, raise that to a thousand. If the manufacturer wishes to remain anonymous in this case, let them make you a satisfied customer as they should.

Peter: It sounds as if the BAT VK-30 can be a handful to own and operate in terms of finding suitable candidates to operate with. I have run across similar products in my line of work. The bottom line in most of those cases is that the owner ends up selling it in order to find a product that is both more versatile and less volatile in terms of the components connected to it. While i still stand by my comments that the original amp had problems, it is becoming more obvious that other brands also "dislike" or "have problems with" that specific preamp.

I wonder if this could be a specific problem unique to circuits using the BAT 6H30 "super-tube" ??? Sean

Peter,

I just happened to see this thread and it reminds me of the same problem that I had with a BAT P5 / BAT VK30se.

I purchased a BAT P5 Phono and connected it to a BAT VK30SE.

This in turn was connected to an ARC VT130se.

When I tried to use my system, my new KT88 tubes started flashing and 3 of them were destroyed. The P5 was the problem.

This started in May and I finally got my P5 back last week. This story is too long to post all of it here.

The point I'm making here is that the P5 had a high frequency oscillation that passed through the 30se and caused all sorts of damage to my amps power tubes.

Also, BAT put on a fix on the P5 to filter DC leakage.
