VTL Service ??

Asa, the only MB-185 Signature I'm aware of is the model I own with 6550 output tubes. I don't know which of their amps may have used the tube you refer to, but I believe VTL streamlined their range down to 6550's and EL-34's at the time they introduced the "Signature" transformer models a few years ago.

I have had no problems with or complaints about my VTLs or the company itself. So far I have only good things to say. I purchased used VTL 450s in Japan 18 months ago (probably 6-12 months old at the time). Several months afterwards, I emailed VTL asking for an owner's manual in English and some advice on biasing the tubes. I got a series of nice emails in quick succession starting only a few hours later (with full docs), despite the fact that it was only 2-3 days before the C.E.S. (I have to imagine for any manuf. that has to be a busy time). If I remember correctly, Bea sent a nice follow-up email several days after the show to make sure everything was OK.

I emailed VTL several times asking if they have a dealer in Thailand and never heard anything from them. It's been over 6 months. So now I gracefully move away from getting VTL amp.

Just my experience.

Zaike, it was a special order unit. Thought yours might be one. It sounds better than EL34 and especially 6550 units. If you ever send it in for service, you might want to consider the mod. Ask around.
