Hi, Just quick stupid question, did not find answer using search... If I choose to drive headphones directly, should I change C22D also to 470uF? Can't decide from description in parts list... Looking at shcematics, I would say that I do not need to change it, only C24D and C25D, but then...

Yes! Finally I got those SRC4192 I ordered from eBay! Funny how it took 20 days them to arrive via USPS while shipments from amb took only 5 days (seller did post them on time, can see it from USPS sticker)... perhaps this one got stuck in customs and amb's shipment did not. But back to...

If anyone is interested, I created BOM calculator prefilled for y1+y2: http://keitin.net/jarpatus/BomCalculator.y1y2.xls It's pretty crude and simple and probably has some errors (didn't verify prices etc. and of course I have never programmed with VBA before and to be honest, it's most...

And another one lives, after having some problems with γ1 full++ and finally solving them all I had to solder missing op-amp and caps to γ2 and plug it in. And it works! This one is AD8656 with Panasonic ECA0JAM471X 470uF output caps, no bypass caps currently (plan to do some experimenting...

Hi again, Any words of advice? I finished my gamma1 full++ build but I am having strange problem - playback volume goes up and down by itself (not OS or amp volume, but perceived volume). Also when I don't play anything, I hear small pops, perhaps more when I tap the PCB. Of course this...

Quote: Originally Posted by Draguljce I presume that idea was to make a small trade-off because default part list uses panasonic for output coupling capacitors which are presumably less good sounding that some "fancy" capacitors and those bypass caps should compensate for this...

Hi, Just quick question about C19 and C25... Parts list says 1µF metallized polyester capacitors "or metallized polypropylene (MKP) in a lower capacitance". Does it actually matter what I throw in or is it "up your personal preference"? I am currently building gamma2 and just remember that I...

Hi, Just quick question, would it be bad idea to use PANASONIC ECA0JAM471X 470UF 6.3V as C20 and C26, because I can't find those recommended Nichion KW or FW caps anywere and I may wan't to use gamma2 without amp occasionally. Dimensions seems to be the same (well, Panasonic is 0.2mm taller)...
