Except that this might make what happened in your PS look like childs play, instead of 2x the rated voltage we'd be looking at ~5x or more. I'm going to try hacking the jpg file this afternoon to see if I can fix it. It's been a bad Monday in the office though so for now the warning is the best that I can do!
Thanks for sharing the schematics with the DIY community. Looks good!
Dr. van Waarde amp concept is clearly visible: cathode follower (via grid stopper resistor), but with 2-halves of a 6AS7G in parallel, feeding by higher B+ voltage.

I've updated the schematic to fix the C3 mistake - however it may require folks to clear their browser cache to see the correct image file. I did a direct replacement of the image file so that I didn't have to change links so the old image may show up for some folks for a while.
Many many thanks nate for posting up the PSU schematic. I am happy to see that an OTL tube amp that sounds as pimptastic as the reviews indicate can be built with such small value caps. You are an inspiration.

Thanks for posting the details. This looks surprisingly easy to build, making it that much more accessible.
It's too bad I blew my budget already or I'd move this up to #1 ahead of all my other half built stuff.
Just remember that schematics can be deceptive and that the devil is in the details. Casework on this project not only requires a fair amount of time but tools as well. Assuming one were to use the same caps that I did you'd need to have a drill press and several different sizes of hole saws. I'd say I spent well over $100 just on tools to complete this build and the fasteners weren't cheap either. The raw parts cost that you'd get by looking at the schematic really only hints at the total build cost. All the same I'm working on a BOM with sources and prices, not sure when I'll get it done or posted though.
Thanks for posting the diagrams.
