6V6's in a Mark II

[jacobcarpet]

Anyone given this one a try? Switching out the 6L6's for 6V6's and plugging an 8 ohm speaker into the 4 ohm tap? I haven't taken voltage readings on my Mark IIB yet, but then again I've never needed to take the chassis out of the cabinet. Tesla 6V6's have a voltage rating of 500 vdc so there's no problem there. I'm just wondering what it sounds like and if anyone's given it some thought.

I don't know if the voicing of the Mark II really lends itself to 6V6s really.

Theoretically it's fine to do it though - follow the instructions in the Mark IV manual; IIRC that means you'll need to have the amp switched to class A, and it won't be possible to run 4x 6V6 on a Simul-class Mark II like you can on a Mark IV because you can switch all the sockets to run in class A which you can't do on the II. But a 60/100W Mark IIB should, in theory, be fine.

Of course the next person to post is going to explain why I'm horribly wrong, but I think the above logic is sound. You could always ring Boogie?
