Benson Monarch build

That looks beautiful but to be honest i would also love to have a look at that schematic. Too loud for me, but i am always interested in special circuits.
 
I’m in the same boat about volume. I’m using a Weber Mini Mass attenuator to keep it down to home levels. Next build will probably be a Princeton 5 watt.

If you want the documents, send a private message.

Also, for anyone taking on a similar project, some of the resources that helped me in terms of safety, the order of operations, etc, was the following….

Rob Robinette has a lot explaining circuit design, mods , safety , etc.

Rob Robinette's Car and Tube Amp Website

Mojotone has manuals for a lot of circuits. I read through their 5e3 manual to get a good foundation.

And Fazio Electric is perhaps one of the coolest people on YouTube, and she works on some pretty amazing gear.


I probably should have put a disclaimer on the beginning of this thread, but there’s some pretty serious voltage running through tube amps, and I don’t think you can read too much or take too many precautions when it comes to safety with this kind of project.

Where'd you find the schematic/layout for this? I just started building amps as well and this looks like a great build.

Oh man I’ve been waiting for a schematic and layout for this amp since I first heard it. I’m also too new to PM. Any chance I could get a copy of the documents?
 
Curious if I could get any info on the benson build? I’ve been researching and building around what I’ve found. Looking to cross reference. Thanks!

Yo,

I’m finally getting around to trying my hand at building my first amp, a Benson Monarch.

Thanks again to demetris who was able to get me a layout and schematic.

It’s still a work in progress, but here’s where I’m at so far…

I measured the components, created a chassis template on Apple pages, and printed it to scale.

By covering the chassis in painters tape and gluing the template down, I could use it as a drill template.

Please ignore the fact that I originally had heater wires running to the rectifier tube.

I also screwed up and cut the template for the wrong power transformer, so I made an adapter plate for the correct transformer.

If you still have the schematic for this, could you possibly DM it to me? It won't let me send you a direct message.
