Help with tubes for my VTL amp.


I need help with re-tubing my VTL Stereo 150 amp. Does anyone have recommendations on this amp on tube brands for tube compliments of 6550C, 6350, and 12AT7?
Thanks.

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?
