Default DIY Tube Microphone preamplifier

Hi Group:

We've finally got the Gyraf/GroupDIY G9 tube micpre off the ground:

It's a real-tube dual mic/line/instrument preamp with P48, HPF, and phase reverse. All you need really.

The documentation is complete, with all plans, PCB layouts and schematics. No strings attached. Free.

And - the best of it all - it's made with easy-to-source components..
