My mains voltage is 122.9VAC at my workbench. Using a 25VA 15V+15V Avel tranformer, I get 17.5VAC loaded at the secondaries. The max output I can get out of the of the Placid (@200mA) is +-21VDC.
I think 15V is fine.

Thanks Brian. So, assuming a 4V dropout, that leaves plenty of headroom even with a 15V transformer. Good to know. I think I'll use my 18V transformer elsewhere and buy a couple of 15V ones from you guys. Edited by user Saturday, September 26, 2009 2:01:55 PM(UTC)

The Placid is just capable is drawing more current than the LCBPS, so we wanted to stock a transformer which will suit a wider range of applications. Put plainly, you can power both side of the Buffalo (analog) with one of the (old) 15VA 15V+15V transformers and one or two bipolar Placids.
If you are going to use two Placid BPs for dual mono, it would make sense to also use separate transformers. It is not required, but if you are going for optimum configuration, dual supplies and a single transformer is sort of going half way. Two transformers will get you galvanic isolation between the channels. That said, this is a smaller upgrade than just switching to the Placid from the LCBPS, which will be a more dramatic improvement. How about the Placid for driving digital section? Does it run ok with the "old" 9v+9v transformer or is the newer 30VA transformer required/recommended for that?
