RE: Filter caps 5670 pre amp

The reason for these things are 2 fold. One is that someone got a mess of cheap 12 volt transformers they are trying to use in production. The second is that they are trying to get around UL issues by making it able to use a 12 volt AC wall wort instead of plugging into the wall directly. This seems like the former. I have used this power supply once to build a S. Bench tube tester where you use the 12 volt for heaters. The power supply was supposed to be saggy and tolerant of faults.
