Popular DIY amplifier threads

[carlmart]

I am returning to the idea of building some high quality solid state power amps, powered by +/-50v or 60v, that have not FETs at the input, or MOSFETs at the output.

For the latter I have my reasons, for the former I couldn't find a dual-FET being sold by Mouser that could be used on an LTP pair, even with a cascode.

Suggestions?

I cannot suggest one based on your preference, but here's an old list of popular amp builds..

Cheap amps ? Power ? Are you willing to go SMD , at least partially ?
Wolverine is the nicest , but the "proper" overkill build will be >500$ USD.

Can be 100W 8R / 150W 4R if you do overkill.
Cheap input stage SMD <10$ , output stage = <30$.

The only way I got my wolverine built , is with "collected" parts/used case. Too poor for >500$.
Spooky = modern "LEACH" - Hellraiser is a NAD like current feedback amp - infidel is a simpler Wolverine.
ALL are low PPM (clear - and precise). first two are servo'ed.

If anyone's still interested in a quality DIY amp kit, see also the ultra low distortion LDA17 amps. Besides a simple turn on thump muting via a mecahnical relay, it is also available with protection circuits via ultra low distortion solid state relays.
