Default Ready to ROCK !!

All 4 pairs are installed and tested , just have to do a little millin' on my heatsinks. Lined the NJW0281/0302 pairs up at 4 -1/2" - 114mm (pix 1) and the
MJE15032/33 drivers at 4" -102mm. These amps look like they were made for the heatsinks (pix 2) . A lot of precision drilling and tapping , I use 6-32 allen head bolts with load spreaders and strange orange insulators that came from the genesis stealth.

All set for tommorrow's FULL power test from hell. 2 paralleled speakers per channel , same as the "supersym" test. With the GX's higher gain I will most likely approach the speakers "death zone"

OS,

You are truly welcome. I'm glad it arrived and survived. I consider it a paltry dues for all the good you share with us.

It is a funny transformer , I wonder who "yuki" is ?? I will share more now that I have the PCB problem "licked". I share a lot , but there is something strange afoot. Many download my designs but do not give any feedback. I would be more than glad to help with any aspect of something I designed.

Next , I need to redesign a simple soft-start , I will share the whole experience here. I will use the little salvaged microwave trafo and a few other simple parts (darlington , simple RC delay) to make a compact , reliable unit.
I don't want this one to rely on the main power supply to be triggered but to be enabled by the AC line directly AND to be self powered.

BTW , Ed ... i see you are a speaker man. I eventually want to design a 12" peerless 3-way super speaker to match my amp. It would need to be most robust , as my amps can easily spit out 500w peaks.

Default Top dog !!

This is what I will be dealing with tomorrow(below). I am even impressed (very hard to do) at the professional look of this amp. I am glad there will be no "finger crossing" or any other B_S to look forward to as I have already biased and listened to the units ... NO SURPRISES.. Except maybe some awesome headroom and superior stereo imaging (I have only heard these in mono so far )

OS, I have downloaded some of your stuff and appreciate what you share. I am not there yet with prefabricating my own pcb. I have been researching on it and in the process of looking for a used laserprinter now. From what I read in your previous posts is that I should be looking for a HP printer due to the toners lower temperature? I have been thinking for some time now of going your route and build a universal PSU and try different amp builds. This DIY does get costly and this is what I've experienced with the different builds that I have done or attemted to finish. This includes and not limited to 3 amps (SkA 150, Blames ES both done, Lynx 60%), 2 Linestages (Heretical 90% finished, Aikido 50% finished), just got done with DCB1 buffer.

The funny part with me is that new things always pop up and I tend to jump from project to project so the finances for parts are always jumping around also.

I used to have a Dodd TUBE amp and preamp, I sold both for about 4k a few years when I stumbled to this site thinking I could have more for less. In the long run I figure I will probably spend more but at least I'm getting an education at the same time, plus I really enjoy it, and I get to try different flavors.

Thanks for what you share, and I will definitely be looking at your progress with this amp and will look forward to building your designs in the future. Too bad you don't offer boards but this is DIY....

That is the reason for the "mongrels". Once you get your power board and power supply done and bolted in , you don't have to go broke and build all those projects anymore. I will eventually have Voltage boards up to A "ZX" , if I wanted to , I could even turn all of mr. carlos's DX amps into voltage boards and run them at 60 or 200w+.

Each voltage board costs less than $10 , so DIYing can be less expensive. Also , my FR-4 is "bulletproof" you CAN NOT lift a pad from my military grade PCB's .... you have to scrape it off.

I will be selling boards in october (GX,AX,BX,CX , PB250/60- PS100) all made by me , not chinese board house stuff.
Below is the AX , I had to take parts out to finish my GX's , but it sounds golden. It is still the champ in Wahib's simulation "shootout".

I knew you would ... I have left the iron on a small pad for minute(s)
while scrapping some old boards , I wanted to destroy the pad but could not.

MG chemical's FR-4 will not de-laminate or deform in any other way as well ,a little more expensive but a very good product.
