KT88 tubes for Monos

Wolf, I'll bet Ry Cooder knows all about tubes! As for the KT150, high-powered amps are completely out-of-fashion with the best guitar players. Low-powered combo amps using EL34's or 6150's is all that anyone plays. To get the tube saturation and over-drive guitarists want, a KT150 amp would be way too loud. Now, a bass amp might be a good use for the 150, 'cause bass players want clean high power.

Here's too much information: bdp24…You’re correct sir, exactly why I said "make a KT150 based BASS amp?" After around 5 decades of pro guitar playing, I currently mostly use a rare Reverend Goblin 5/15 watt 6V6 push pull all tube combo amp with a Jensen Neo 10 (actually 2 of those Jensens as I also have a single 10 extension cab that makes the Reverend even better sounding), and a Burriss Royal Bluesman tube rectified 18 watt class A single ended EL84 head with a Mesa 12 cab. Mesa currently makes great tube bass amps, and I was around for their early 80s beautiful 400 watt bass amp (a GREAT amp) but, again, no 150s yet. WHY WHY? My bass amps are a 150 watt little Eden Nemesis 12 thing that sounds amazingly good, and a retro Ampeg class D PF series 15" rig that’s sort of adorable (amp flips over into the speaker box like the old ones…cool). I’m doing a gig with Jim Campilongo soon and he’s made the classic Fender Princeton Reverb his thing…12 watts maybe? Small guitar amps rule man…oh yeah…uh huh...

Why- simple. You play guitar or bass- maybe you go on tour. A tube dies. If its a KT-88 its a simple matter to nip down to Guitar Center or the local guitar guru and fetch one up. If a KT150 you are so out in the cold...

Yeah…if you tour (although most bass players don't) you better take extra tubes along, especially in that KT150 amp I now am certain somebody will build due to the popularity of this thread (!). The SVT has to get the award for longevity as they're STILL used all over the place, although the full size 8X10 cab is a real pain to haul around. We use a 4X10 "half stack" at some of my mixing gigs and that thing is way more reasonable and sounds fine.  My PF series "flip top" rig got a LOT better after the 15 loosened up, and the thing is a conversation piece for sure…and inexpensive…6L6 tubes in my '61 Bandmaster were my first tube experience and I'm not sure I EVER changed those…for years…and I hauled Twins Reverbs around…too damn heavy...
