Because my Stax SR-404 Limited is now one year in his box without using...
...i start a new project, based on the fabulous circuit from Andreas Rauenbuehler on high-amp.de
The Transistoramp V4.0
My pcb´s are ready and now i am collecting the parts.
A set of wonderful teflon Stax Pro and Normal jacks, i´ve got from a group buy on Head Case.
So stay tuned...

My last dream come true!
The output cap upgrade to the holy grail...
DUELUND´s CAST PIO Copper Cap!
Therefore the Tube-I-zator must go to the 2nd floor
Sound review
Now after ~150 hrs. burn in time, i will share my impressions with these outstanding caps.
I had a déjà vu after changing from my previous Mundorf Suprem silver/gold/oil caps to the Duelund CAST PIO Copper.
The same difference as in my 300B mono block´s.
This openness, clarity, three-dimensionality with so many more subtleties and micro informations, absolute breathtaking.
Only the Duelund CAST has the possibility to reproduce this 3D soundstage

The new Tube-I-zator V3.0
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
