Oh, by the way wanted to thank everyone for the greetings. I will take the advice offered by fullrangeman and purchase rather than build a new tube amp. Or else have my old one repaired. Really loved the modded little Sylvania single ended integrated which recently began crackling in the left channel. A new set of tubes seemed to solve the problem but it still sounded like the left channel was working harder than the right and then started to repeat the same noise after about three minutes of playing tunes. Sigh...
Luxman L100 is a nice looking amp.
Iam 3 years already collecting parts to a 6C33 amp, seems a endless work, just 6 months to find a good vintage knob.
Transformers reach 24kg and need a 5mm alum chassis, no shop sell it, so it need tobe made, my tech amp builder is no more friendly as before etc etc
To worse some US vendors even refuse ship to my country.

And yet I had 4 shipment stolen only this year by the brazilian post guys...
