Hi to all 🙂
After reading plenty of topics in this section I'm still in doubt. I'm going to build a hybrid 12AU7 (tube) / IRF510 headphone amplifier which is powered at 12V and should have a maximum current draw of 400mA.
NP-100v12: DIY 12AU7 (ECC82) Tube / IRF510 MOSFET Headphone Amplifier
I was thinking about a 12V/10VA EI transformer and a sigma-25 regulated supply by AMB Laboratories, built using an LM2940CT-12 12V/1A regulator by National Semiconductor (with heat-sink) and a larger capacitor than suggested (let's say two 3300uF capacitors in parallel instead of a single 1000uF capacitor).

What do ya say? Could it work fine? Thanks in advance 😀
