DIY amplifier for Apoogee Scintilla

Gydotron · 11th October 2004, 04:40 PM

My speakers are Apogee Scintilla's and they are 1 Ohm speakers. At this moment I use a Krell KSA 100 MK II. But I would k-like to build a new amp for Mid-High response. This amp must be stable at 1 Ohm and must deliver around 100 Watt into 8 Ohm. Idea's or schema's are welcome!

Regards Guido

I have heard of a digital amp called "H20". Don't know if the designer will share the schematic. I've read that it'll drive Apogee Scintilla with flying colors.

I want a pair of Scintilla. Know anybody that wants to sell?

with this sort of speaker my immediate reaction is to drive it actively. But i think that approach would loose the "magic", you like/bought the speaker for................

If you find what you're looking for, i'd be very interested to hear how you acheived it......

I just recall recently that I've read somewhere that Pass Aleph O will drive Apogee Scintilla comfortably. There is one for sale right now http://cgi.audiogon.com/cgi-bin/cl.p...ran&1102088433

Since you want to DIY and since this is a Pass Aleph amp, why don't you built this one? Schematic should be on Pass Labs web site. NP might even help you if you need help.

Hi Gydotron,
You can also build a Krell clone. There was a DIY effort that was successful.

Nothing wrong with Nelson's creations either, just watch the heat dissipation for something in the 100W range. His designs are mostly class A types, or at the very least they are high dissipation.

Build the X series clone.

Just the one above mine. Should have looked further back.

Thanks for pointing that out to me.

Hi newfinish,
In future, please post a request like this in "Trading Post". I can't believe you just thread jacked an ancient thread!

Gydotron, maybe you could try this one. Has been built exactly for one Apogee speaker model (don't remember which model) almost two years ago, and work OK. Sorry, no PCB because my job was just to design schematic and the rest has been done by that guy. If you decide to give it a try, I could ask for PCB files?!
