I've been continued on the preamp but it's still some work left before I will start with the fx-loop and the power amp.
Simms Watts PA 100 - from original to monster - New clip!

Sweet!
Henric, Why did ya choose the Simms/Watts over the Laney PA?

I went with the Simms-Watts because it was better suited to a 3 channel layout. According to Henric, the build quality is also a bit better.

Yes, it is beautiful!
All the potentiometers, knobs and switches are in place. Next thing to do is wire the eq for the three channels. And after that I will start with the channel switching.

That looks amazing so far, can't wait to hear the final product!

Very cool platform for a monster build, and very very nice work.
Big tube PAs were & are my fav project to turn into something new and exciting.
To the OP, have you ever experimented with the IXCP 10M45S ?
Seems to have many possibilities inside tube circuits.

Thanks man!
I have never experimented with the IXCP 10M45S. If I would want to take down the B+ in these amps I would need a regulator that can handle over 600VDC, and 450V is not in that range

It's starting to look like something! Just a couple of hours from the first startup. I have put in fuses on the power tubes cathodes, so if one tube fails, that pair (inner- or outer pair) will be switched out so you can continue the gig on two power tubes. A led will light up so you can see that the fuse has tripped.

Henric, that friggin cool... I have never seen that before. What a killer feature.
I was curious on what kind of plate voltage are you gonna be running on the preamp tubes?

Yeah, that is a great feature but it's not my idea
You can see it in some other amps, even some Marshalls.Plate voltage depends on circuit design, I'm very picky with the preamp voltages. There is always a sweet spot where it sounds best. In channel three i use three different voltages and it is over 100V between the highest and the lowest plate volt on that channel.

The amp is up and running! It sounds impressive! I will just give it some hours of tweaking before I record some soundsclips for you!

NICE!!!
Would be bitchin to show-up for a gig with such a beast and have players coming up afterwards going "what the HELL is that thing?!?!?!"

Ya know Henric... In the amp world there are few that take such an endeavor and do it with such professionalism. This amp is a work of art looking at the layout and how you have it wired up. I can think of only 3 or 4 others that take the time and do it this well.
