Blackgate n series coupling direction

dsavitsk · 15th December 2005, 07:07 PM

Somewhere there is a thread where Peter Daniels discusses the best direction for a Blackgate N series coupling cap in a TDA1543 DAC. I have tried all the search terms I can think of, but cannot find this discussion. Anyone have a link?

Simple. Short lead is start of foil - connect to positive rail or input signal.

much thanks.

Yes, that's how I do it too.

And you like these over film caps? I've been using a pair of Jupiter 4.7uF caps (clipped in with alligator clips) which sound very nice, but for space and financial reasons am replacing them with the blackgates -- the jupiters are for a preamp project but are just sitting around right now.

Peter seems to like them a lot. I tried replacing Jupiters with BGN and they really didn't work for me. Could be for the lack of patience to break them in.

Yes, I like them, and from what I hear a lot of people like them too, but mostly in SS applications. Because of slightly warm signature, BG N might work different in tube circuits.

I tried Hovlands, Wondercaps, Musicaps, Jensens (copper foil), MIT RTX (with silver bypases), Siemens MKV, Russian paper in oil, but in my DAC, I preferred BG N 4.7/50 for coupling.

The only cap that I chosen over BG N there, was teflon V-Cap.

They are soldered in, so I'll give them a shot. Out of the box, so to speak, they are a bit clearer than solens, but not nearly as liquid, warm, and sweet as the jupiters or even some sprague motor runs. i'll see what happend with time. (here's my dac project, b/t/w/ http://www.ecp.cc/NOS-USB-DAC.html )

Also, NON POLAR print is always on a side of short pin, so it's possible to identify directionality, even if the pins have been cut.

Peter,

I like the BG N series too, haven't tried the V-cap yet, very
expensive.

Sorry for a slight thread diversion but have you heard anything
WRT supply of these BG caps?

Cheers,

Terry
