Recomendations on build

tvrgeek · 23rd January 2010, 10:27 PM

So many possibilities. I have 2 DH 220's and a 120. I was going to "POOGE" or otherwise mod them. Read all 800 some odd posts on this forum's subject.

But, might as well have an open mind for other options. The LEACH seemed highly recommended. Any other great ideas? Basically, just reusing the heat sinks and transformer. Under 100W is fine, but really clean. Obviously, to better the Haflers, or maybe even my old Rotel's. I might even entertain a small Class A. 20 or 30 years have bound to make some advances. Op-Amps have gotten extremely good, Heck, just ordered $50 worth of parts to modernize a tube amp.

The Sysasym is highly documented and a lot of people here from the forum including myself have built and liked it a lot.

Ah, a gainclone version. Possibility. Also thinking class D, but of the OEM versions of either technology I have heard, not impressed. I will read up on your recomendation. I suspect most OEM designs suffer from the same problems as conventional amps, execution, power supply etc. that can be resolved in DIY. Thanks.
