if you really feel the need, anything can be done at a cost. This extra cost will not contribute to making the amp sound better.
Personally I dont see the value in that.  :nfi:


You are wrong you see.  When you start selling NOS cream of the crop hand selected tubes to your customers at a nice markup for a lot less effort than building an amp, the angst meter, will stimulate sales.

There is value in that, for you, maybe less so for the customer.

Hi all, so it was a nice long weekend and I managed to box the revelation 3. It is sounding extremely good and I am very happy with the result so far. I have to finalise the headphone output and then the lid can come on.


here are a few pics of the revelation 3 pre amp.














PS I have taken Jozua's request to heart and a hours worked timer will be implemeted in the microcontroller and be an option to view and reset on the display.


Regards
Willem

That looks absolutely stunning!

Thank you so much Lanties. It has been quite a job and to do the wiring that it looks halfway decent and still keep the good engineering practices in place is a pain staking task. So I really appreciate your comment.

It's no longer DIY.   Belongs at HiFi show.


Meant as a compliment.

Looks great from a technical electrical & mechanical standpoint.
However, as some total unsolicited commentary from the side, my input from aesthetics would be:
- reduce the darkness and change the font of the Revelation 3; my immediate impression was that it was drawn by hand with a magic marker
- change the font of the power/phones/volume to something a bit more modern (it looks like the old rub-on "Letraset" used on DIY projects in the 80's)

[neither of those need cost anything but can make the difference between the looks of a product vs. qty-produced prototype]

I agree. Sometimes we are just a bit polite around here and perhaps positive encouragement helps a lot but not always in the right direction?. The fonts could be done better.  Maybe get help from a few ladies on design choice on that.
One other thing I would change are the screws holding the connectors.  Use non magnetic stainless hex or star.  It may sound better but will definitely look better too.

Thank you guys, all the feedback is constructive and I will definitely look into your suggestions.


The font is a difficult process as everything is engraved with a CNC machine. The smaller the font the smaller the cutter. That font on the front panel is machine font which means that the cutter does a single pass only allowing for such small font.
Never the less, thank you for your suggestions. This is a prototype so next pass will be better. :thumbs:
