Only one?

Folks, do you ever assemble your amps w/o PCB? It can be messy to make an entire unit because some components end up being loose and need additional support to be kept in place. Units I make now use LM1877 that require a number of external components. I was able to make sturdy design with that circuit. Next challenge is a transistor amp. I use heat shrink tubing to make cases and copper rods for frames.

My 350w/c amp. I just constructed it with locally available parts. I know the looks isn't that good but it performs for more than a year now and I am happy with its clean sound.

is this the one you are talking about?
2sk1058 2sk2221 irfp9240 mosfet amplifier schematic


PS. I did build both the T300 and the M400. They are excellent amplifiers. The M400 is playing right now in my living-room. The T300 is in my brother in law's house. Between both of them I like the M400 better ,it has fewer parts and I like it simpler!!!. But do not get me wrong here,the sound in the T300 is excellent too.all what they say on their site about these wonderful amps is true!!! I strongly recommend them. all the parts are high quality and all are original, the board is made in the USA!!! it will take two weeks to get it in the USA. Just ask for Alfred. He is a wonderful person.
