Hi Jason, i own a V'lux silverface and need to know whats the good tubes too. Freom research I have come to the conclusion that the 6L6EH Electro harmonix are good, The 12AT7s I will use the ECC81 JJ Tesla replacements, and the 12AX7s and 7025 which is the same tube use the Electro harmonix 12AX7EH variety as well. The GZ rectifer tube i would buy a sovtek or EH again. Ive heard this is the golden standard for the older fenders and will give good volume and tone. The red power tube is serious and most likely a bias problem which you should take to your tech to have biased. I would wait and see what the speakers are like after you do that. If you have Jensen C10Q speakers they are the most desirable in the vibrolux. i have those and would never bother with other ones. Im going to take my own advice and will report back on the forum. Cheers Greene
