no not power tubes
asking for trouble if you do that
I beg to differ!
With power tubes, you can swap different brands of the same tube. (For example, 6L6 tubes from different manufacturers.) But do not swap different types of power tubes unless you are absolutely sure you know what you are doing — damage may result.
If you do try that make sure that you re-bias your tubes so that they at least match in that respect. If you can't do that don't try. Even then I wouldn't do it.
Personally speaking I generally select matched power tubes of my choice based on SQ (not so much power ratings) and make more subtle changes to their tone by selection of small tubes.
The only real concern is IF the manufacturer calls for matched pairs being used.
Brand mixing? Maybe if it is an American N.O.S. mixed with a Russian-likely power struggle resulting in blown expensive, aftermarket fuse.
Russians & Chinese are in cahoots so no problem.
"blend the sound" What the heck is that?
it is a dog-eat-dog world in the china manufacturing scene... not for the faint of heart
even among chi-fi brands... denafrips makes a bit of name for themselves, then a related factory nearby undercuts them with the musician brand... different faceplates, cheapened parts, lower price...
kevin has the primaluna’s manufactured in china, then cut rate knock offs of those at 60% of primaluna models appear not long after, direct sales from china...
