RE: Help me ID this ST70 mod

Posted by xaudiomanx on March 15, 2016 at 21:39:29:
Many tube mods for the Dynaco were done using three input tubes to replace the 7199 tube. The CAE mod always used standoffs on the input board attaching it to the chassis. I really don't know all the boards out there but the CAE from my past knowledge used standoffs. If it has them it could be a Curcio. I also think Triode Electronics used them as well now thinking about it but I think Triode Electronics has it's name on the bottom of the board.

What tubes does it use on the board?
