I didn't point it out earlier on the spread sheet (as you are not replacing it it does not matter), but C7 is 0.0002uF (200pf) as in the 'Service Manual' you linked to, in the 2nd diagram 0.00002uF is a typo. Again the value of C15 is vague, but as you are keeping the originals it will not matter. You will see better when you remove R5. Likely 15pF as on the service manual diagram. The 200pF (0.0002uF) value is associated with the addition of R23 which yours do not have. Could be when the change to the 8778 output transformer was introduced. Yours have the early 3921 transformers.
