There is a lot of confusion about caps' values.

The current sch in our repository shows the 5, 11 and 13 caps as 0.015uF.
The part numbers for 11 and 13 is 3615-E, and according to Ray's book it is 0.05uF
Same value is shown in the Riders sch.
Now the part 5 is 3615-F.
Again, our sch shows 0.015uF, Riders is 0.05uF and Ray's book shows it as...0.006uF.
Notice that this is the only 3615 series part in the book that is not a 0.05uF. Some of them have resistors etc, but all will have one or two 0.05uF cap. So I think it is an error in the book.
I will use 0.05uF.

Plus, I think the way this cap is, it is not really important there; either value will work fine.

PS. South-Eastern Antique Radio Society sourve shows 3615-F, AF as 0.05uF.
PPS. Also Chuck Schwark's Repai Bench also shows it to vbe 0.05uF.
