Velleman K4040 Amplifier (Tube)

216.13.52.5

Hi Dave,

Sovtek tubes sucks, hein? Your right, they are usefull when you test the circuit, because if it explode, your ears will miss nothing! I'm too interrested in that amp, but I wonder why it use three triodes before output stage. I see a driver stage and a phase splitter, but can you tell me what's the use of the third and what's the role of the 12AX7?

Speaking of 12AX7, try a Raytheon round plate from mid 40's or 50's. Yum!

You said that the chrome ring will not fit with some tubes. Can they be remove easily?

Thanks again for the review and enjoy the rediscovered music!
