Hello all...

I'm re-tubing my Peavey VMP-2 mic preamp. Currently it's set up with its
original set of Chinese-made tubes. Although it has relatively low hours for
its age, I'd like to give it a fresh start with some NOS tubes or
equivalent.

Each channel uses three 12AX7's and one 12AT7. No problem finding decent
AX's; pending the response from this group, I'm planning to install new
Groove Tubes 12AX7M's. (Has anyone had any experience with those?)

But I need some advice on the two 12AT7's. Where's the best place to get
them, and what brand is the most like the old U.S.-made AT's?

I'm concerned that installing garden-variety 12AT7's will undo the benefit
of adding the expensive GT preamp tubes.

Thanks in advance for your responses...

Alan
