I found some pictures of version 2 from the front. None of the back panel unfortunately.

watz, it's going to be many shoes, or maybe with the rand dollar as it is now not so many if they are also imported  :winkwink:


I did a pricing check on the BOM and this is what I am willing to build the pre-amps for. I am quoting in Dollars as that will take away the fluctuating rand issue.


Only the best quality components are sourced and used.
Version 2:
Tubes - Amperex Holland
Signal Capacitor - Audyn Tri reference or Jensen paper in oil depending on your preference
All resistors are specifically designed for audio use
Electrolytics - Nichicon and Elna
All hookup wire - Jupiter 4N copper in cotton sleeve

Version 3:
Tubes - Siemens Germany
No signal capacitors
Transformers - Lundahl Sweden
Resistors - Vishay foil
Electrolytics - Nichicon and Black Gate (yes I have stock of these)
All hookup wire - Jupiter Silver wire in silk sleeve





The models are called Revelation 2 and 3 with Revelation 2 (v2) being 2/3 of the price of Revelation 3 (v3).


Revelation 2: $1000
4 stereo channel single ended inputs and 1 stereo channel single ended output.


Revelation 3: $1600
4 stereo channel single ended inputs, 1 stereo channel single ended + 1 stereo channel XLR balanced outputs.
Headphone output.
Remote controlled input selection, mute, standby and volume.
Full dual mono design. Two separate high voltage extremely low noise power supplies, one for each channel.


The components used in these designs are not merely thrown in to add a snake-oil factor. Each and every component was selected in its position with many hours of a painstakingly voicing process.


Regards
Willem

Hi, I am about a week away of posting pics of the completed revelation3.
I have been listening, burning-in and voicing / tuning it for about 3 weeks now.
The case work took a long time to sort out. But I now have that in place so it will go much quicker from here in.


In parallel I got an order for one of my 'RIAA resolve' phono pre amps so that kept me busy too.


Here are a few bad pictures of the revelation3 in the making.








Cheers
Willem

Looking very pro and creating high expectations but then I am easily pleased with the very best...

Suggestion: Can a valve hours worked timer be placed inside to valves hours worked - to make it so much easier to know when the valves need to be replaced.

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:
