C+ Through Mark IV guys, do you use all 6l6's? or el34's in your outer slots?

[Fusionbear]

All 6L6's in my Blue Stripe MKIII. But I converted the outer sockets to full pentode and got rid of the voltage divider in those sockets so that all the sockets are wired the same. I also added a bias pot.

Want to mention that there is an art to using 6L6's in the outer positions. The sockets run hotter, so I would use colder rated tubes to compensate. Of course I've tried hotter tubes as well...just because I want to hear changes for myself.

Dave is right. I have extensive bias data from a whole bunch of Boogie amps to learn what tube ratings need to go where.

Triode is next level

Sylvania 6L6’s. Never cared for the EL34’s in the outside sockets.

Same.

 

[SpiderWars]

I always preferred all 6L6 but EH6CA7s in the outer sockets sounded a little better than EL34s to me.

So does that make it 120W now?

Can you share some of your findings?
Im deep in the rabbit hole for sure
Wanna narrow my tubes down

It has that potential, but it will always be capped by the rating of the OT ultimately. Haven't measured mine yet, but its got to be 100 watts for sure. I love the tone I'm getting with it through my old MESA half-back cab...

Help me, I don't understand what you mean...

What amp?

 

[stephen sawall]

All 6L6

 

[Dopethrone]

What amp?

M4a str441 pres: vos handpicked by me
M4b 440/447 pres are Mesa
I like both as is, im just curious by nature!

I don't want to clog up this thread with data, email me ferberphoto@yahoo.com & I can share my IVa and IVb power tube testing with you.

 

[JimAnsell]

clog up the thread! no one cares! either way, emailed about mark IV data

Got it. I have power tube test data from 20+ Mesas...
