And a pricing quotation so we know its Euro worth too. Interested here.

Yes please!

Thanks,

Regards L.C.

Sure. It will only be a matter of hole placement on the heatsinks.

I will let my friend Bert make the drawings.

This is an excellent amplifier and deserves an excellent chassis!
Depending on the cost, very interested.

I hesitate to post this because I'm not sure if it's good or not. I've included three attachments. One of the Lazy Cat TSSA BJT circuit, second, of my pcb layout with component values and third, my pcb layout without component values. I layed out the pcb's in a program called DIYLayout Creator. I've been using it a lot for simple guitar stompboxes and small power amps. I know that I should just bite the bullet and learn Cadsoft Eagle. I was hoping someone could take a quick look and see where the glaring errors are or if I should just scrap the whole thing and use a better pcb editor. I've seen the layouts that Ales MM and a few other do here and there so good. (Beyond good). I just wanted to etch my own all bjt version of the TSSA and listen to it. You won't hurt my feelings if it stinks.

P.S. 1mF FB bridge cap can be also beneficial.

The same circuit could use njw0281/njw0302. With an higher idle in the input pair (10mA) and with good cooling it would be easy to do a class a amp with them also. Maybe even remove the collector resistors??!?!!!

Hi All.

I have made an powersupply design guide.

I know it is based on my modules but, I have added comment about fuse and wire dimensions.

I hope it is useful.
