Hello DIYAudio members! Everyone who has been following me on these two threads, http://www.diyaudio.com/forums/solid-state/174468-very-best-amplifier-i-have-ever-heard.html , and http://www.diyaudio.com/forums/group-buys/175296-pcb-order-goldmun-clone.html , I will from now on will only post here. To everyone else, please enjoy the ride.
I've been in the audio industry for 10+ years and have heard everything from Levinson, Bryston, Pass, Ayre, Rotel, Boulder, Cary, and 90% of all other audiophile manufacturers. I've never heard anything to even belong on the same league as the Goldmund Mimesis 3 amplifier. The design is state of the art, the sound is world class. Everything else doesn't matter.
The goal of this project is simple: To clone the Goldmund Mimesis 3 amplifier 100%. I will not take any suggestions, or upgrades on the circuit. Not negotiable. Only on the PCB layout and construction of the amplifier.
Here's where this project stands and where it will be heading in the next week:
1.) Please see the original, 100%, accurate schematic of the Goldmund Mimesis 3 and the protection circuit below.
2.) The PCB layout is nearly completed and I will be posting it early next week. The basic layout remains as Alex has created, with the now correct parts to reflect the Mimesis 3 amplifier, correct part sizes, correct lead diameter holes, etc. I will be posting the complete part list early next week as well.
3.) I will order a pair of the PCB boards from a high quality US manufacturer. The order will be placed the following Monday after Thanksgiving Day.
4.) I will build this amplifier step by step on this thread, with pictures and explanations. The PCB boards will be tested for quality, functionality, fit of parts, etc. The final amplifier will be tested on a Tektronix.
5.) Goldmund Mimesis 3 has the following power rating specs: 100 watts (2-8 ohms) and 200 watts at 3 ohms. The rest can be found here: GOLDMUND MIMESIS 3 STEREO POWER AMPLIFIER - SPECIFICATIONS
6.) NOTE: All electrolytic capacitors in the schematic have the + shown as an empty rectangle and a - as either a black filled rectangle, or a line.
This is an amazing project that rarely comes about. I hope everyone enjoys it
