The new Tube-I-zator V3.1

Click the image to open in full size.

The evolution brings the following changes:

- Anode PSU with Salas SSHV Shunt Reg. onboard
- External B+ Input for usage with other Anode PSU
- Heater PSU with C-R-C filtering
- Heater PSU with Softstart circuit
- Heater PSU Power LED

- Design failures corrected

Thanks to John (-ecdesigns-) for the following suggestions!

- Grid stoppers to prevent unwanted oscillations
- Bias current injection for TDA1541A usage
- Pull-down resistors to keep the coupling cap output at GND-potential

Still on the Module:

- Heater switch for 6N2P or 12AX7 usage



An example for a balanced use (e.g. Bufalo II), you could see HERE.



The PCB has the following data:

Material: FR4 - 2mm

Well my friends it is time again to say thanks to all of you, who like and ordered my pcbs.

Because i am no developer of electronic circuits but have the knowledge to design pcbs,
i wanted to give something back to the community.

Since i started with my 1st pcb, the Optical-Volume-Control on 15th October 2009,
a small donation from every sold pcb goes to diyaudio.com

Today i am proud to say that your cumulated donation achieve

$ 3104

Keep on having fun with my pcbs and best regards
