probably does not matter on this amp, but soldering the tabs on those transistors on the ssdynalo makes a fairly big difference to getting the heat into the heatsink plane

so that actually looks like an overheated pin due to poorly tinned wires (or no tinning) or not screwing down the wire tight enough. Seen this on too much expensive lab equipment. So the pin overheated, then all sorts of bad. The trace it was shorting to is the feedback line and is close to 0 volts

grlv boards will run perfectly without any load

one bridge if you are running a 3 wire transformer, 2 bridges if you are running a 4 wire transformer

you just had to point out the yellow chair... i'll bet it stinks too.

But there are 4 power supplies, 5 counting the bias. What you want is a series of detectors that detect + 15 volts +/-.25 volts, -15 volts +/-.25 volts, +400 or +450 +/-10 volts, and -400 or -450 +/-10V that all requires an extra board with comparators, voltage references and a number of other parts.

the led's drive the current sources. red only, and do not extend for any reason.

use black magic marker to make it all black, then add some messed up funky logo's plenty of room to add flying piece of shit kobicon output connector

well that is a better idea than that magic pixie dust that the one company fills its stupidly priced cables with... and then leaks white shit everywhere

customized case is what I was thinking of. I have the tools, what I don't have is enough time at the moment I have had the previous version running at 300ma on now for at least 6 months 24/7 no problems

where is steve when you need him? one man's floor is another man's ceiling

well that depends, if its close to 200 proof, even the 150 proof stuff, will burn very nicely. And you won't be able to see the flame.

40 years ago, they held up well against everything out there for the same price. As I remember they were $600 a pair. The JBL's were a bit more, and the B&O 5700 were also about $600 a pair.

I wish I still had my ns1000, but they fell apart... ns5000 is $10k per pair? am I reading that right...

here is the latest amp board picture without the ground plane http://gilmore.chem.northwestern.edu/kgsshvcarbonv6.jpg with ground plane http://gilmore.chem.northwestern.edu/kgsshvcarbonv6g.jpg and latest schematic http://gilmore.chem.northwestern.edu/kgsshvcarbonv5.pdf and two of the many power supplies http://gilmore.chem.northwestern.edu/kgsshvcarbonpsleft.jpg http://gilmore.chem.northwestern.edu/kgsshvcarbonpsright.jpg older power supply schematic without the on/off switch http://gilmore.chem.northwestern.edu/goldenreferencehvsic.pdf

that board is 5.47 x 3.04 inches

"output transformers" ?? needs a wood knob. I can help with that.

40? that scares me unless you are using it to drive speakers. even then its a bit much default gain is 10

once you have the usb stick prepared, trivially easy. About 2.7mb/sec i will be moving the pioneer under my main monitor so its going to be way easier than ps3 about 30 megabit per second on a gigabit network

ssdynahi more than happy to take se input and convert to balanced

the 180 has a different chipset and will not work. the bdp80fd is also known as a 170 or 160 outside the usa and works

a standard S22 would smoke at 3 amps at 30V

bought a pioneer bdp80fd brand new for $300 from b&h people should buy them now before they are all gone. SO MUCH EASIER than Piece of Shit overheating version 3 garbage and if you have a modified PS3, time to dump it before its worth absolutely nothing. also have tested 103,103d,105,105d in case you have one of these. even with the multiregion hack, still works

ss dynahi and its easy to modify the gain. what's not easy for most people is all the chassis work. The same people sell the boards and all the parts for a price that I cannot even come close to in the usa.
