    New Pio in the house. I bought this little SA-500A cheap, in working condition, reading 15,5mV on left channel and 12.4mV on the right. There are no infos about BIAS settings, so I think 15mV I have in is the right value. Of course, it will be recapped. I usually use Nichicons for recapp, but I...
