I have a Mark V combo. I've thought about trying EL34s but I like using the 10w mode sometimes. From what I have read it is not a good idea to mix 6L6 (outside) and EL34 (inner sockets) and run in 10w mode.
Can I pull the outer tubes (6L6s) and just run the inner sockets with EL34s and have n trouble in any watt setting? Of course I know to flip the switch to EL34 bias, but I'm guessing that only using 34s it wouldn't hurt anything if I used either bias.
So, can I mix and run in 10w or just use the inner sockets and EL34s in 10w, or should I pony up for 4 EL34s?
Also, I usually buy JJs but what would you recommend for an early cleanish, edgy tone. I noticed that JJ has a "blue glass" E34 with more headroom, same voltage here: https://www.tubesandmore.com/products/e34l-jj-electronics-blue-glass
The TS has a JJ 6CA7 and an EH 6CA7 high voltage. Are these the same as the "good" 6CA7 tubes? I've never used any of them.
So, 4 EL34s and 10w or two in the middle with empty outer sockets, or 6L6 outside, EL34 inside and 10w?
Another question, well two... what "number" should I look for in a matched tube, like (I forget which tube store sells matched tubes and numbers 1-10) what number is best for a MV?
Since the MV is, I think fixed bias.. is there a way to adjust the bias or would I have to change a resistor? ..and would that be a BAD idea? I ask because I had a "boutique 6V6 powered amp. A four holer design that would, if I slammed it hard with humbuckers cut out. The builder dropped the plate voltage to try and fix it BUT after that "fix" the amp lost something, lost it's mojo if you will. It always makes me wonder if biasing hotter or raising the plate voltage just a little will ADD mojo to an amp.
The Mark V is so complex I hesitate to even think about doing anything to it but a POT (which is a variable resistor at the end of the day) makes me think about adding one to control either bias or plate voltage, small range of course. Yeah, I probably should have asked this in another thread, I'm asking for drift but... yeah, there are really only a couple of questions here. EL34s and 10w, tube rating, and changing the bias or plate voltage. The last are probably bad ideas but nothing asked, nothing answered.
Thanks. My main concern is EL34s and 10w mode. I suppose I can use either or both in 45w or 90w.
