Valvatron 250 watt Valve Amplifier Demo

[@ralphups7782]

I bought a sugden amp, a few years ago. it totally changed the way how I was listening to music, so I must say this . I take my hat of to all engineers who are from every were around england and not just down here in London

Nice one Paul, thanks for showing us the circuit, it looks beautifully built!

[@richbrown5852]

Stunning point to point wiring, craftsmanship!

[@ralphups7782]

fantastic stuff, keep the good work up Sir's and more power to your elbow.

Ahh! Now we're talking! Talking of talking, I love the way we Jamaicans and our Yorkshire brethren both say, "likkle". I inherited some huge valve trannys from an old sound system amp and am looking to build my own valve amp with an older friend who knows about this vintage. Looks like 88's would be the way to go then for reaggae? Anyway, likkle more...

Always good to see your innovations.

[@captmcgravy2669]

beautiful sound. looks like a Pro Heathkit and it's lovely.

[@davidphillips6543]

Beautiful work Paul. Do you spec sheets for all your products? It would also be great to see a video demo of the speakers. Could you do a demo of the complete sound system you sell? It would be great to hear how the full system sounds.

[@Axissound]

Hi. I dont have a spec sheet, hopefully soon on a website. Any specs you need, just ask. I would like to have a vid of the full sound, but its all selling out very quickly and dont have much chance to get a full sound video. For performance specs, please email [e-mail] Thanks.

thats a fantastic sound

[@d3dde76c]

It looks great, with great quality parts and an excellent building quality, but the main transformer and the output transformer without shield and parallel to each other? What's the output noise level? pretty sure you would have a lot of 50 Hz and related harmonics in the output signal. Is there any bandwidth, noise and distortion measurments of your amplifiers online?

[@Axissound]

There is very little noise and no 50Hz harmonics. The transformers only need inverting if there is such interference, but there was none in the prototype, so none in here either. No measurements online.
