So I decided to build my own version of the ST35. I really liked DIY Tube's use of the 12AX7 and 12AU7 and incorporated that. I also implemented Dave Gillespie's EFB mod.
I'm using a Shunguang 12AX7 I got for free, a nos RCA clear top 12AU7 and Valve Art EL84 power tubes.
Oh and for the record I had used the box previously as a preamp hence the holes in the front.
It was challenging integrating the circuits and coming up with a layout and ground scheme. Thankfully once I worked out my initial troubleshooting and missed connections it worked like a charm. Sounds pretty good too!

Here I'm using my iPod Touch, Bottlehead Quickie Battery-Powered Tube Preamp with the new amp.
Thanks for giving me a challenge and for sharing all of your posts and experience. It's been a tough time recently and this project has helped me in many ways. I'm really happy with how it sounds and looks.
