53-956 Philco
#6

Looking at my notes 11 pages 38A used a 22UF at 50 volt 38BCD 47UF each at 220 volt,  items I try to have  on hand. Replaced CR with 2-1N4007, R28 increased to 50 ohms. The reason for the change in R28 the CR would drop voltage by 7 volts the 1N4007 only drops voltage 7/10 of a volts. My 12AT7 tube only worked on AM but not  FM. The 19V8 tube worked  Ok replaced with a NOS what a difference, other tubes ok. This was a project from May-July of 2011. Nothing in my notes on problems with installing the replacements for 38ABCD. Stay Safe David
