hoping to have more PCBs and kits available around the end of March, and will offer upgraded output caps (AudioCapTheta)
and of course ANY parts can be upgraded!   Meanwhile, check out our preamps

Hi Bob (?), welcome! The ST-35 look interesting, I hadn't seen that before. I was wondering about the chassis compared to the original ST-35 and then I remembered what a pain the original cramped chassis was.

Boy, does this take me back in the wayback machine.  My initial dive into tube amps was many years ago when spotting a pair of Dynaco MK IV at a garage sale.  Cleaned up the chassis, put in a new board, wires, and caps.  I always thought the Dyna MK IV was the best sounding of the old Dynaco line.


Good luck with your business.

I actually bought one of the VTA ST35 amps, it's really nice sounding.  I posted about it here:

I believe that's Roy Mottram posting.

I've got more PCB kits in stock and chassis in stock, now waiting for more transformers.   
Also updated my page and upgraded transformer options.
