I built a 1w easy once - your stuff seems more advanced though.

I'm Subscribing! - really looking foward to seeing your progress.

Good luck man
Thank you.

Getting back to business, since you two (soloz and Grim) have both done projects like this before and I respect you guys and your work, what do you recommend in solder? I've done some research and have figured out that I want leaded, rosin-flux solder, but that still leaves me with a ton of options. Any particular brand that works especially well, or am I fine with just about anything?

for pcb work I really like Kester I use their no-clean I think #240 series. It's a little more expensive but you don't have to clean it up and i'm lazy. lol. their #44 series rosin core is probably the most recommended for DIY electronics.

I'm also a huge fan of Cardas Quad solder, but you can pay upwards of $75 for a 1lb spool of it. I've used it on boards before and the Kester is easier to work with and cheaper, but the Cardas does give you that nice shiny finish and sounds great. Plus you have silver, copper, lead and tin in it instead of just lead/tin so it will give a more uniform connection.

I think I'll be going with the Kester on this one. Is #44 really that hard to clean up, or is it just that #240 is that much easier? Although the 44 is certainly much more common, I could pick that up locally.

It's not that hard to clean up.

If this is the only project u need solder for I could send you some for a fair price. It's cheaper to buy in 1lb spools so I've got about 3/4 lb of each

I might just take you up on that. 1lb is certainly way beyond my needs.

I'm finding the Decibel Dungeon to be incredibly informative. The guys there seem to have covered everything, from upgrades or recommended components that deviate from kits to little things like where to put in fuses that don't seem to be mentioned anywhere else. Kudos to these guys, I'm spending hours reading here.

After quite a lot of research and self-debating, I think I've finally found my semiconductor.

The real question I faced tonight was whether to use the LM3875 or the LM3886. They are incredibly simmilar, both loved by most who try them, both 11-pin, both with full protection circuits, but I decided to go with the LM3875 because of the combo of higher output and higher SNR. (Granted it's only 95dB compared to 92dB, but it's still a difference) Now I've just got to find a kit based around the 3875, and I'll be good to go.

In other news: Here are some pretty pictures of the chips and basic PCBs. I have not started my own construction yet, but you can be sure that

Last update untill I start getting parts in:

I've got an order in to Parts Express for assorted soldering supplies and a tube of Kester #44. Once that gets in, I'm just waiting for BrianGT to get the rev 3 PCBs in stock. Updates as the UPS man brings things in.

National Semiconductor is awesome. I ordered 2 samples of the LM3875 Sunday night, and this morning the UPS man has a box for me marked "URGENT" that was sent next-day air. I call that service! I did not pay a penny.

National Semiconductor is great aren't they? Also, buy from Digikey. Super cheap, and very fast shipping. I've been making amps(guitar, bass, line, stereo, headphone) and effects (rack and stompbox) for a couple years now. My most recent project was remaking a Fender Princeton(6v6GT power tube). If you have any more questions, I could probably help out.
