I ask this question here because you guys seem more interested in speakers than amps. I've found, that except for tubes amps, I don't find much difference in good amps anymore. I'll even admit that I find cheap T-amps to be pretty good.
So, I'm finding I need lots-o-amps from 50-150 watts. What's a high value single channel way to buy amps? I don't need a nice box, or a brand name.

"GainClones" using LM3875/3886/4870 op-amps are pretty popular and can be built for about a dollar per watt.

I've never built one, but I've considered it SEVERAL times.

Me too. My modified Metaxas presents music differently to my friend's MF, which was different again to a borrowed Quad SS we heard in the same system. The differences were pronounced and significant... and this does not include chip amp or digital(ish) topologies etc.
As an aside, the 'old' Metaxas smashed the new Quad (and MF) in just about every way that mattered to us. Interesting. Ah, but I do look forward to going SET.

Here are some high power T-amps I haven't seen before:

Here's the popular parts express amp

It would be interesting to compare the T to the Parts Express AB design

Just ordered one of those. Even for just the chassis & power supply probably worthwhile. Doubt it will stay stock.

There is some nice solid state out there, at a cost. So, chipamp if you need decent quality and decent power for a modest investment - you can do them in a way that does not cost heaps. Otherwise tubes, with - I believe I will ruffle some feathers - DH tubes offering a little something special (and perhps greater overall potential), if one seeks to exploit it. I have been planning to go the way of tubes for too long now.

Suggestions for:
Gainclone kit???
Tube amp kit.???
I would need an easy build. With a lot of instruction. And photos. Maybe need video. Perhaps a little man that pops out of the box with a soldiering iron..........
I've started to wonder if the Parts Express tube amps are a good value. I've come to realize that the PE people are not idiots. (For some reason companies never reprint my endorsements )

For tube amps I would recommend the Bottlehead amp kits. The instructions are great and so is the support forum. If you want to start with something low watt without a need for a preamp look at their SEX amp. I have one and love the sound. Also Decware sells good tube amps. They are put together for you except for the one kit they have. One nice thing about them is they are in central IL and close to me.
