My 8 channel LM4780 power amplifier.. :D

Oh yeah, and the main thing, how does it compare to lm3875 in terms of quality? If it sounds worse, or about as good as 3875, no use for me to build it. I don't really need heaps of power (unless of course I decide to build a 5 or 6 channel HT amp, in which case this would be a PERFECT candidate!)

The quality should be the same as the LM3886.... or so the datasheet suggests....

Where are you getting your components from?

Im here in Adelaide also 🙂


what parts are you refering to? 🙂

Good quality caps, heatsinks, etc.
The harder to find stuff.

maybe I can try making my own PCBs... I mean, I'm sure I could set myself up and make the 4 PCBs for less than $140....

I make my own PCBs... i can do double sided (not plated-through hole tho), with accuracy of 7mil.
Anyone with a decent bubble jet printer can, no other special equipt needed.

wanna get a 3unit rack mount case? 🙂 if we can find 4 people they are $97.95 each.... one would normally be $109... but if we can find 10 sales, they are only $86.95... 😀

Hmmmm.
Actually, i think i will be needing a new 3U case soon, and i do like the Jaycar units.

wow, netscape really sux.. lol and this keybord is just the worst, and why would anyone use Windows NT.. 😛 anyway.. lol

Good quality caps? ohh, umm.. lol I wasn't really going to bother... lol all I really need is power, my speakers are bad, if I apgraed them, I will ungrade the caps also.. 🙂 (yeah right) the capacitors I do have came off ebay... heatsinks I will probably get from Conrad heatsinks or just Dick Smiths..... transformers came from www.oatleyelectronics.com thats about it...
