Reference DAC PSU
for Red Baron / Tube-I-zator

Custom made "Galaxy" housing with 10mm front panel from

Custom made Transformer with double C-cores, made for Vacuumschmelze Germany for Siemens military equipment

Tube-Rectifier circuit (6106/GZ34 or equivalent) with High-End Parts for B+ of the Tube-I-zator

The C-L-C-R-C Network with no electrolytic caps!

Yamamoto Teflon socket

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.

The new Red Baron

The evolution brings the following changes

- Jumper for I2S / simultaneous mode
- latest 3.3V attenuator for I2S & simultaneous mode (by -ecdesigns-)
- free running DEM oscillator (by -ecdesigns-)
- additional U.FL pads for I2S & simultaneous mode
- Separate U.FL-GND route to Digital-GND

Still on the module

- Separate I2S-GND route to Digital-GND
- Separate Analog Output GND route
- Separate GND route for active divider decoupling caps to Analog-GND
- Modified active divider decoupling pads for better SMD 1210 caps soldering
- Un-interrupted ground plane
- Direct shunt voltage inputs with shortest onboard traces
- I2S In-/Outputs with shortest onboard traces
- Onboard Grounded-Gate MOSFET Current Buffer I/V Stage
