That thread is still open but not popular now. I still have some boards for them. If you are not serious, do not ask me to send invoice. Too many chicken-outs (after issuing invoice) .

Thanks for sharing!
If anyone can help me to furnish my BOM, please do so. Some of the components may not have a proper rating. For those who had finished and experienced, please comment on those ratings and make it easier for those who are going to work on this project.
For the 4.7pf caps on the main board, will 5p be as good? Thanks.

You will be very lucky to find a vendor that supplies 5pF +-10%, but there will be some.
The designer who specified 4.7pF probably also knew that @ that value most caps have a very wide tolerance range.
It is not easy to measure a 4.7pF cap to 10% !!
Without reading through 197 pages of posts, could someone give me a brief rundown on this amp? Things I'd like to know:
1) Power output
2) Total cost (not incl. custom PCB) of parts
3) Recommended PSU or at least required input voltage
4) Performance compared to other DIY amps of similar price

Here is something to chew on ,,,not sure about cost, compared to other amps Well nelsons are a GREAT amp been around many years,WHO'S sounds best I haven't heard both in a A,B comparision and there are valid points of designs from both sides ,build one and see that's the DIY way here!
Hi ,
Today I finished Goldmund 9.2.
The sound is ... fantastic!
Very very accurate and fast, with a dynamic is great!
I am very happy
Once again - thank you all on this forum for help!
Best regards!

Mimesis 9 2X50V AC
input 1.55 rms 2.19 p-p
What is the actual resistance feedback value which defines the support at 175 watts
The plan of the amplifier shows two resistors 15κ-10κ to give result 6Κ who in relation to the resistance value 330Ω give a gain value Χ 18,18
Resistance value 8,2K relation to the resistance value 330Ω give a gain value Χ 24,84
1,55 rms X 24,84 =38,515V X 38,515V =1483 / 8Ω = 185 W
when i put 8,2k i get more wide square wave and the sound more clear/
Any advice please??
