Peter, I received the classic GC kit today, I will be looking forward to "building instructions for a complete NEWBIE..."

I am hopeful the new thread will have minimal schematic but truely a beginner's guide with lots of pictures. I know how to solder but can not read schematics at all...

May I suggest the rectifier board?
More than half the efforts on this thread are Q&A on how to plug in the amplifier, with much less questions on the amplifier itself.

I think its good to start with that because it can be puzzling, and because the rectifier board is quite durable--better for first time soldering on that part (practice) than on the amplifier board.

So, after getting a way to plug in the amplifier, thoroughly explained, and after some practice on putting it together, and after checkout with a voltmeter, most people will be "home free," as in well on their way to an amplifier.

After that, keeping the DC out of the speakers.

And finally, putting the amplifier into the enclosure to finish up.

...... ' with what to start with'.

Dan says the rectifier board. Newbees have no idea what a rectifier board is.

May I suggest a simple explanation of what a gainclone is followed by a glossary of nomenclature?

Peter -

Mine came as well. Thanks.

I plugged it in and it doesn't work. What did I do wrong?




.... Sorry, couldn't resist.

I was thinking that it might be helpful to describe the basic component building blocks -- both what they look like on a schematic and what the actual physical devices look like, how to orient them, etc. This would allow people to start with the usual first steps of inventorying parts, etc.

I started a new thread here: http://www.diyaudio.com/forums/showt...49#post1508749

By request, here it is:

Beginner's Gainclone with
LM1875, LM3875, LM3886, all on nearly identical circuits, and all as simply as possible.


No copying--this is a new design.
No PCB to ship--this design works quite well on phenolic veroboard or eboard, available anywhere.
No brand or price specific components--the design is "hardened" against component variety, so you can use available parts.

Yes, it has general compatibility with sources and speakers for the expected good results, regardless of speaker and source varieties.
Yes, its very low cost.
Yes, its easy, and its ready.

Yes indeed!

To do this, I need to split up the topic into:
1). Amplifier (LM1875, LM3875, and LM3886)
2). Power
3). Chassis
And, each on its own seperate thread.

Starting off with LM3875, here's the thread: http://www.diyaudio.com/forums/showt...postid=1509662
