So if I understand the question correctly, you're risking doing damage to an item with a used value around $1k rather than just buying a new set of tubes? Do the math and weigh the prospect of having to pay for a repair bill vs. buying a set of $100 tubes. The amp isn't designed to operate with different tube types, no amp is, though it technically could. The answer seems obvious to me. Buy a pair of new $100 tubes and avoid the risk of doing damage to your $1k amplifier. I can't believe I'm even responding to this...
PrimaLuna ProLogue Two - mixing tubes?
I have a newer quad set of SED 6550Cs that I've been using as a replacement for the stock KT88 tubes. I decided to take advantage of the auto biasing feature of this amp and run one 6550 and one KT88 per channel, only because one of the stock KT88s is bad. I'd like to use up the other two good KT88s. I've read that this is acceptable with this amp, but I'm not sure if this will have negative impact on the 6550s. I plan to rotate the 6550s so that I still have a somewhat matched quad set of them. Has anyone done this before, and are there any pitfalls I should take note of?
Thanks
