Also, feel free to post pictures of any Tubelab project, not just the Simple SE. Creative chassis ideas aren't limited to one circuit design

Thanks! Don't want to have to build one of those again...

Well, the TSE still needs a chassis. I put it back on a breadboard to try some layout ideas:

Here is my version. KT88 power tubes EDCOR 15w5k8 driving 4 ohm speakers. Will probably upgrade OPT but sounds good enough that I am not in a hurry.
I also attached the chasis for my Tubelab SE. Was experimenting with inlays. Will make top plate tommorrow. That will have 25W3.75k6ohm edcor custom OPT and 300b power tubes.

What is the cost ( roughly ) to build one of these Beast's ( stereo build ).

There's a pretty huge range depending on parts used. This was my first DIY project so I had to buy EVERYTHING; soldering iron, multimeters, wire cutters/strippers, EVERYTHING. When all was said and done for me I think I'm looking at nearly 800 USD. Now, that includes a lot of different tubes as well as some fancy wood for the chassis.

If I only had to buy parts I think I probably would have spent around 500. I ended up spending about 300 just on the iron (transformers and choke). I think 500 is probably somewhat close to the top end of what most people spend on parts; I've read of people doing it for much less and if you've already got some spare parts around... 35 bucks for the board?

You can easily build on for less than 500$. I can't!!!!. Even if I need one piece I usually will order 5, hey that OPT is 18$, but look I can get that one for 30$ and it goes to 40hz. You get my drift.

For less than $500 you will have an OUTSTANDING amp with the added benefit that you can say you built yourself. The only thing is to make sure your speakers are sensitive enough. I was happy initially with 87db but alot of people wouldn't, particularly if you like to bang your head. I am running 90db today and it is certainly loud enough

EDIT++ I am running kt88 at 450V for about 7Watts

Thanks guys, i wouldn't know where to start, i guess ask Planet10 for some stuff maybe buy some stuff from him, buy parts here and there on ebay. Id like to build a low budget one then when i can afford it buy the better stuff, I have 93db efficient speakers ribbon tweeter and a 6.5" i run 4 amplifiers now, 2 aleph minis per speaker, so i would have to build 4 of these amps,

And that's how mine ended up costing $800! I was a little different though. "This amp calls for two of these caps, I better get 4 just in case I do something wrong and blow two of them up. Oh, and it can handle 6L6, EL34, and KT88... I better get some of each, just in case..."

I started out thinking I could get a great amp for cheap; well I'm pretty sure I'll end up with a great amp that "punches above its weight class" but it won't be dirt cheap. Part of that is the slippery slope mentioned above, part is the fact that I really had to buy everything as I've never DIYed anything before.

Now, back to pictures!

The amp is stereo. Should only have to build two if I understand your post. You can economize easily in this set-up. Use a cheap OPT for the tweeter and a mid size for the bass. What it the F3b on your bass?
