The reason I mention it is that I had a set that was recapped by someone that miss wire a cap in this fashion. Should have been across the line not across the rectifier. It had a terrible hum. After checking the tubes for shorts and the filter caps I saw a cap across the 25Z5 socket wasn't shown on the diagram wired like that. Rewired it to B- and all was well.

Vol 1-50 admiring the old set and trying to
