What's the SIMPLEST 50W or higher Amp Schematic but best sound you've heard ?

calico88 · 15th January 2007, 02:08 PM

Does anyone ever heard/built the simplest 50Watt Schematic Amp and the sound is best ever heard ?

I'm sure you can suggest me where to look.

and it's cheap and all the component are easy to find, like the Output transformer.

I want to build this, dosn;t matter wha't the sopology... as long as everyone agree for the sound, money and easy to find component, specially the output transformer.

show me the schematic

You ask the impossible.

GOOD sound is directly related to high quality O/P trafos, which are EXPENSIVE.

Since cost containment is a high priority, consider building speakers whose efficiency requires less power from the amp.

The Dynaco Mark III probably qualifies, as it's 50W and about as simple as they get... kit will be available Dynakitparts.com. I don't think you can beat the reproduction Dyna transformers for the money (just like the originals were the biggest bang for the buck...).

I would use a different driver circuit, but there are boards available for various circuits. Ready-made chassis at Triode Electronics, transformers too. If you are planning to make your own chassis, the EIClone from DIYTube.com is another possibility...

Transformers: http://store.triodestore.com/dytr.html
Mark III circuit: http://www.geocities.com/vintageaudio/markii.JPG

The output transformers are probably the best for the money. One other possibility is the Hammond 1650N, though I don't think it's as good (no direct experience though). Edcor has a 60W transformer for only $67 - http://www.edcorusa.com/products/tra...4_8-4_2k.html, Again, no experience with this one.

With Edcor or Hammond, I'd suggest less gain in the preamp stage, which means correspondingly less feedback (less chance of oscillation).
