Does Tweed Power mean 6v6's are a go? Yellow Jackets + IIC+?

Here is a question for all you techie types out there. If an earlier Mk series amp has Tweed Power switching, can a guy just drop in a quad of 6v6's like one would on a MKIV? My Simul-Sat had Tweed, too, but I never tried it out when I had it. I am sending my IIC+ to MB at MB for its 25 year check up (time to replace those stock tubes maybe?? :lol: ) and was mulling a Tweed Power mod if they offer it so I can get more power amp voicing options for low and mid-gain tones. I almost bought a Heartbreaker head beacause I am wanting to go low power MK style and find the class A 15 watt setting is still not allowing much power amp saturation, but decidied to put the money into my IIC+ so I can play it every day and use it as my main recording source (headshell time - I'm too old to carry that **** 1x12 EV combo anymore :oops: :oops: :oops: how lame is that? ). Any thought on how to throttle down the Beast? Anyone use Yellow Jackets in their MK series 100 watters? I am not a fan of attenuation and love the sound of tubes working hard. My 20 watt Subway Blues about 12:00 is perfection, so I want to see if I can drop the big boy down into that range. Thanks in advance for any help. Z

Well, if 15 watts in "Class A" is not enuff, then how would four 6V6s be better? That's gonna to be about 40 watts.

Anyone find the 15 watt mode still way too "clean"? Z

You still have to crank the master to get power tube saturation.
And the first Volume control should be at least at 7.
Are you running EL-34s or 6L6s in the outer pair?
EL-34s should break up sooner.
 
Try some yellow jackets in the outer sockets and then run the amp in class A? Worth a shot. Your IIC+ is a 120v model, not an export, correct?

I have wanted to try two 6V6s and two yellowjackets in a Mark IV in tweed mode. I wonder how it would sound?
