I concur with Casouza completeloy I had my MC100B for a couple of years now and must tell you that the best value for money on power tubes are the Sophia Electric sourced GEKT-88 a sweetheat of a deal the KT88-98's are not that great, too bass heavy and they shout in the mids. they shione on teh top end but it's 1 of of 3 while the GEK's do all things pretty good.

now if you wan to invest some serious $ into tubes the NOS 6550 TUng-Sols are the best bar none, the comes the Ei KT-90's pre conflict I thik type II's are teh best bass you can get out of this really good amp for the money.

I particularly enjoy it in triode mode, I think UL is only for rock & Roll, definetly triode is a lot more musical, better mids amazing stage end pristine clear top end.

As far as the KT120's I sincerely think the oputput tranny's are warm enough with the KT-88's if you push them harder with KT 120's you are likely to se early death due to metal fatigue or worse.
I'll put in GEKT88 and take teh rest of teh money and put it in some serious 5751 for the input tube This ampl simply loves them especially GE black plates 5751 amazing!!1 and soem good old 6SN7's like tung SOl tall bottles or Ken -Rads 6SN7-GT.
I have a few pairs of the RCA's gray glass, Ken-Rads 1940's, tung-sols 1950's tall bottles and some Sylvania, Raytheon and Tung-SOl black glass I trasure them all as they all bring something different to he table.

Mind you I have a lot more $ on tubes that I have on amp. you can imagine.
Nowadays my preamp has developed a hum that I haven't been able to get rid of so . . not listening to this combo much lately.

But I sincerely would not put KT-120á in it too many good tubes to buy into the hype of the KT120s, especially if you want to hear whatthe best this amp can do is most definitely into triode mode.

Hope this helps;

Gonzalo
