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

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
Layers: 2
Board size: 193x157 mm
Surface finish: Immersion Gold
Copper weight: 70µm
Soldermask: Both sides - green
Silkscreen: Legend on top

Out of production

The price will be as followed:

Professional 2-Layer PCB: $30
Worldwide shipping: $ 9
Europe shipping: $ 5
paypal fee: 3,9%

Shipping insurance on buyers request!

A donation of $3 USD to diyAudio will be done for every pcb sold.

A 2nd small failure in my design program needs to expand one of every heatsink mounting holes a bit (1mm).

These two small design failures will be corrected in one of the next batches.
Thank´s in advance for your understanding!
