You have to look a bit closer... The polarity is also indicated. C and A stands for Cathode and Anode for the zener and the plus sign is for the LED. You can also compare this in the schematic.

Per Anders,
I'm waiting for my SSR03 boards to arrive but have been looking to source the components. What would you recommend for the obsolete BC546C/BC556C. What would be the lowest Hfe and frequency transition you would recommend for a +/-15volt board with AD825 and LM431

Hi Peraneders,
I'm putting 2 boards in one cabinet and would like to go with a star ground.
One board will be powering 2 Linkwitz LX521 ASP's and the other board will be powering an additional LX521 ASP plus another 2 ASP's for sub woofers. I run balanced interconnects in and out of the ASP's but wish to minimize any potential ground loops by using a star ground arrangement with the 2 SSR03 boards.
Regards
Mike

Peranders,
SSR03 up and running powering my ASP's for Linkwitz LX521 ASP's and subwoofer ASP's. Only problem was a "bad" resistor value from digikey, labeled as 56Kohm, actual 3.8Kohm, changed out for correct value and everything OK.
Sound is definitely cleaner versus the simple 78xx circuits I had before.
Thank you
