Just picked up a Maz combo at the Philly guitar show with V-30. Plugged in my Zvex BOR tonight and noticed I have a microphonic pre tube. Took it out and there are no markings at all. Even more surprising is no tube chart. Don't even see where one had been, no torn paper etc. Rest of amp is mint, has 15 year anniv. sticker on chassis, serial#N 9125. Other tube is a 12ax7, so I am assuming the microphonic is the 5751. The microphonic tube is in V1 (closest to the input jack, and the 12ax is to the left,looking at amp from the back). Any info on tube position, good 5751's and age of amp would be greatly appreciated.

You'll have to click on "old" since the Mazerati is out of production now. But it definitely says that V1 is a 5751.

Thanks for the help. Have a few at7's around, will try them first. A hair less gain would not hurt, although I am not sure of what's in there now. Either way, really enjoying the amp.

The original Mazerati's had an ECC83S in the V1 position and a 5751 in V2.
I just checked my '04 Mazerati (version 2), and it has a 12AX7WA in V1 and a 5751 in V2. And this amp can sing!

Makes sense since the version 1 Mazerati was a double-powered Ghia.

I'd love to have at least a glance at your valuable data. Any chance? TPM
