The FUtracer – A Better Tube Curve Tracer
What is the FUtracer? The FUtracer is a tube curve tracer designed to work with your computer. Now you can get consistent and repeatable results.
The Tube Socket PCB – What Tubes Can it Test?
The tube socket board is setup for you to test: 12AX7 etc., EF800 etc., EF86, EL84, EL34/6L6/6V6 etc. The new 2022.9 socket boards also include a 7 pin socket for 408A and similar tubes! You can also create your own tube configuration if you prefer. The FUtracer itself is capable of significantly more tubes than this, but these are the most popular. You can either create your own socket array, or run additional sockets off the socket PCB if you require other pinouts.
External PSU PCB
To keep things safe and simple, the FUtracer set includes a PCB to connect an external power supply and protect your tube tester circuit.
