Mezzabarba Apocalypse 200 vs Mesaboogie IIC+ : Clash of the titans !

It’s actually a pretty crappy tube. It suffers from the same issue of 6550s but it’s way worse - it doesn’t like a high screen grid voltage but loves a high plate voltage (225V vs 450V). You’ll have to run it in full pentode and with a dedicated screen grid supply. You can’t get away with triode strapping a KT170 as it’s a fire risk with how much current the tube can draw. From a Quick Look at the datasheets a quad of them would also dissipate 25W just in heat from the heater filaments. They seem to like a lower plate voltage too - around 400V or 450V.

It gets its power from how much current it can draw per tube. You’d need a power transformer capable of 550V at 1.5A with 10A 6.3V heater filaments. For comparison most guitar amps are 450V at 0.35A.

It really is a HIFI type of tube. I’d recommend against it for guitar.

Big tube good.

So let's say we start with the ideal transformer for a KT 170. Knowing that they operate best at lower plate voltages could someone make a simple circuit around that like a tweed or a twin reverb and be successful? What about some kind of high gain amp? I'm not thinking some multi channel jack of all trades amp with a lot of features but more of a one channel one trick pony.

I've looked a little and the only company I've seen use a KT 120 is Wizard. I haven't seen anyone in a guitar amplifier use a KT 150 or KT 170 yet. I've heard/read many great things about them in hifi gear so I'm hoping guitar manufactures get with the times and try to make something new and fresh with them because it's a great opportunity. I'm crazy enough to get an amplifier with a sextet of KT 170s but I just need to find the right one for me.

Just call and talk if you have the money.

DAR amps had like what, KT200s in them.

Remember that hifi crowd runs everything at class a low load not to get distortion. Pussies

I know better and I wouldn't waste the guys time on something like this. Most I've spent on an amplifier so far is $1500 Canadian on a Mark III Coli. Good luck getting money out of me.

I'm in the fantasy phase right now thinking about wild things that are far beyond my own abilities. For something like that I'd probably find someone locally who's knowledgeable and passionate about audio but has never built a guitar amplifier before. Lots of those guys love to play around and tinker with things and I'd like to see what could happen if I took a chance. It's not something I'd be heavily invested in or have high expectations or hard feelings over.

There's still hope for some of them!

Damn, when and how you found a Coli for those money? Find me one too please haha

About five years ago I just happened to see it for sale on kijiji and I was about the tenth or twelfth person to see the ad. Told the guy to take down the ad and I met him on the side of the road without testing it and gave him the money after asking if it worked. I got lucky on that one.

That is so cool man!

Reminds me of my first Tinder date.

$4800 and no midi options. Thats getting into wizard territory without wizard resale.

Anyone have gut shots of this PTP work?

Pretty nice shit.

 

[glpg80]

Pretty nice shit.

That’s that good shit. Looks great.

I’d be interested in grabbing one on this used market and then using it as a cheaper mod platform than a SLO to turn into a fire breather.

Basically, it's a Decatone with MIDI for this one in the picture. He changed the grounding schem after that video of Jason's. You would turn it into a ripper man, it wouldn't take much IMO. Just slight change in filtering on the PI to tighten up the bottom end..
