Thanks. I Googled it.

Found it on the ASL website (or that of an ASL dealer). This is apparently a very unusual preamp with 2A3 output tubes that require output transformers or alternatively the large coupling caps. Surprising that the transformer outputs do not sound better than than the capacitor-coupled outputs, where the caps are electrolytics.
