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. 🙂
DEAR ALL READER,
I HAVE LOADED ONE AMPLIFIER PICTURE WHICH IS M400,MN55435 USA PCB USING.MOSFET ARE 2SK1058 AND 2SJ162 .I WANT FULL DETAIL CAN ANY BODY HELP ME.THANKING ALL.

is this the one you are talking about?

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.

dear lanchile,
thanking you for sending such type of amplifier picture.i have two pair of mosfets.if this was in pdf form i will make it and enjoy on the eve of new year.it is very hard to me to ordering it will take more time sorry for my bad english for this reason i can not express my feeling.thanking you your ever masood alvi.

Sorry, but I do not have the pdf for it. I ordered the kits and they did not come with pdf. just the parts list, voltage setting and some tricks.

Wow. Those transformers are master pieces. Very nice job...wait, it is not a very nice job!... it is an EXCELLENT JOB!!!😉
