Help with tubes for my VTL amp.

Please note that you will void your warranty from VTL if you use any tubes ther than what they spec. AND one of those tubes CAUSES a failure in the amp. Not saying don't "tube roll', just be aware that if you do and a tube CAUSES a failure, that failure will not be warranted.

Just be sure to get your tubes from a trusted source, like Upscale Audio...they thoroughly test tubes prior to selling to the end user, so a failure is unlikely.

Meadowman, does VTL test the tubes that their vendor/s provide?

I can answer instead of Medowman that Yes VTL tests the tubes and adjusts them for their amps. They just cost 1.5x...2x higher than you can get it from upscale.
