Question 3: Although the manual calls for a 47Mfd capacitor (RF board, C73) all I have is a disk capacitor marked 4.7. Is this the correct one? Question 4: RF board C71 & C174 calls for an 82Mfd but the only ones I have are 820s. The same? Question 5: Are NE602 (U10 & U11) the same as NE 612? Thanks in advance. WB7SBD de ed #03838
