Thank you very much to all About the tubes, I found them some time ago on ebay, and I bought 3 pieces of them Bye

Do you thin that I can have a better audio quality using this cable instead of the ipod headphone output? Using this cable, I can bypass the ipod internal power amplifier?

Hello, this is my starving student, it works great

Hello, which temperature do you have on your heatsink? I'm testing a single heatsink for both mosfets, this heatsink is 9x5x2 cm, so is not small, and I have more than 60°C I know that it isn't a dangerous temperature for the mosfet, but I think that it's too high

Where to find constant current diodes? Is possible to use another solution? Like LM334 or discrete solution for constant current? Bye

Is it possible to see complete schematics?

Are schematic and project details avaiable?

Hello, I've seen that the 19J6 tube is very hard to find, so I've a question Is it possible to use other type of tubes with 12.6v filament like ECC82 or ECC83 ? They need 150ma like the 19J6, so if I add a resistor I can use these filaments with a 19V supply For the original 19J6 : 19V...
