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
Layers: 2
Board size: 193x157 mm
Surface finish: Immersion Gold
Copper weight: 70µm
Soldermask: Both sides - green
Silkscreen: Legend on top
10pcs. left in Stock
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.
