For the price that amp is probably ok. As mentioned you could build something better for the same price. Though it can take quite a bit of time to build something that is refined enough to be a permanent part of your system. At least if your as picky as I am. Personally I would purchase that amp then build another one if your heart desires. That way you won't feel rushed on the build. Plus, you can never have too many tube amps

I can heartily recommend the TubeLab SimpleSE. If you have some basic tools and can solder it is a peace of cake to build and will cost you around half of what that parts express amp is selling for. It only took me a couple of days to build mine (it is the one on the builders amps section of the tubelab site). I am extremely happy with mine. On the TubeLab web site my comments mention that there is a very slight hum with this amp. I have since discovered that this hum was due to my slack routing of signal and power wiring behind my entertainment unit (I have emailed George to notify him of this). The amp is virtually dead quiet. I have tried the amp with JJ E34L tubes and JJ KT88 tubes. This amp sounds sweet!

I built this simple KT88 single ended amp and have been very happy with the results. I would guestimate power at around 6-7 watts. I`ve compared it favourably against some fairly well known designs and it did very well. Highly recommended.

I'll second this - the Simple SE is about as easy to build as a DIY amp can be (everything's on a single small circuit board), more fun than buying an amp, and a bunch cheaper to boot. I can only hear a faint hum from mine if my ear is brushing the speaker cone. Why buy Chinese?

I'm going to take the advice given and make the TubeLab SimpleSE my first project. Has anyone gone through all the logistics of ordering the PC board and parts that might give me some pointers? The website doesn't look very automated and I'm trying to figure out how to order what I need.

Thanks to all for your help.

George's website is not automated at all. E-mail him and tell him which board you want. He takes payment by Pay Pal.

There is a full BOM with suggested parts to populate the board on the site, that should get you started. Some things you'll have to figure for yourself, like switches, input jacks, binding posts and such. And a chassis.

Well I just ordered the bulk of the components to populate the PCB. (SimpleSE) I don't know what anybody else thinks about the online ordering systems these parts suppliers use but I find them rather frustrating. I have a question about the 8 pin octal sockets. I could not find it on AES but found this:

http://www.tubedepot.com/sk-8pinpcg.html

This seems to be what I need. Does anyone know of a 1-stop shopping website for these parts? I still have to order the power trans, output trans, volume pot, etc. (All the stuff not on the PCB.)

I apologize if this question has already been answered in another thread but could not find one.

Those will work.

I don't think there's a truly one-stop supplier out there. I used thetubestore.com (sockets, 12AT7), DigiKey (500 V Panasonic caps, screw terminals, misc parts), Allied (power xformer and choke, cap clamp, other misc parts that DigiKey didn't stock), Sonicraft (metal film & Mills resistors, Sonicap coupling caps, RCA's and binding posts), ebay (Transcendar OPT's, motor run cap), Lowe's (grommets, nuts and bolts, spray paint) and Linens 'n' Things (heavy aluminum roasting pan that I used as a chassis!).

I still don't have a decent photo of it, but here it is:

Hey Lousymusician, Thanks! I got most of the stuff ordered that populates the PCB. I like that Linen and Things idea. The chassis looks great. Maybe I'll cut a piece from that cooking sheet and use it as the deck in a nice wood frame. (Got plenty of oak laying around.)
