The new Tube-I-zator V3.1



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

Now the digital input section is completed!





Wave I/O for USB input --> SPDIF/AES input board --> FIFO --> Isolator board -->
Dual Clock board with Crystek CCHD-957 clocks (powerd exclusive from a A123 Systems LiFePo4 cell) -->
Ian´s I2S to PCM V2.0 Module --> Red Baron



Because i use two Red Baron´s parallel, i added two additional U-FL connectors for DR and DL.
