Wondering if that extra capacitor in the signal chain between the two modules is necessary?

Here is a clearer image. well, two BC559 are yet to be placed in it though... :P

Hi Guys

Here is my latest amp module hot off the press.

Looks neat

Do you know you can make a thread with your amps in "Vendors Bazar"
Would be much better place for posting your company news

"Do you know you can make a thread with your amps in "Vendors Bazar" ..."

Good idea! Do that too!

For myself, I like to see the latest prototypes, where ever, when ever, which ever thread, even if they may eventually end up in production. ... Especially if they might end up in production!

The Saint's work is always of great interest. In this case, did you notice that the power output MOSFETs are on the bottom of the board? ... Using the board itself as a part of the heat sink? ... Fascinating! ... and a testament to alternative thinking, originality = how does he do that? Must be a real thermally efficient design, fur sure.

It looks like the MOSFETs could or would also be mounted using the board through holes to a (heat sink) plate. That's also a nice tight, space saving trick ... good mechanics, worthy of examination by any serious DIY type, here and elsewhere.

Hi Eddy

The MOSFETs are mounted about 3-5mm off the PCB so the PCB doesn't get very warm. its a fairly low power design so the thermal
issues aren't really issues with this design.

" its a fairly low power design so the thermal issues aren't really issues with this design ..."

Compared to what? The "Death of Zen" above? ...

I know, I know = the purpose of the whole "Death of Zen" concept is absolute attention to best distortion & best quality, not necessarily power or thermal considerations ... but ...

Just finished my first discrete solid state amplifier (a pair of monoblocks). They're pretty basic, with a paralleled TIP2955 / TIP3055 output stage. The hardest bit about designing the amp was fitting everything into the compact case, but it worked in the end.









The heatsink / PCB assembly slides out to allow biasing, measuring servicing etc., pictures three and four show this. The PCBs are my own design, made specifically to fit the case.

A good trick to make the edges meet nicely, is to make a chamfer of 1mm. This way the edges looks like they're lining up perfect, even if you have a slight misalignment.
