I have labeled the VFO just to make it easy to identify connection points. 6-volt pin is not
used.
(1) Cut wires on left side of EL-34 to approximate length. Note there is a ground between
every connection. Since the wires are short and all go to the same basic place, I opted to
leave off one ground as it would be redundant in this application.
(2) Cut RG-174 (or equivalent) to length leave short service loop, and solder the center con-
ductor to the VFO output pin. Remember any wire cut to length will be to short!
Solder the braid to the convenient ground lug sticking off of VFO. This is where the two
coaxes with yellow sleeves go.
Basically, just hook in parallel with these coaxes.
(3) Unsolder wire from pin labeled CLAR in Figure 7 which comes from the wiper of the CLAR
pot. Solder this wire from the CLAR pot to the wire coming from pin 2 (CLAR In) of the EL-
34. Use heat shrink to insulate.
Solder the wire from pin 4 (VAR, Control Voltage Out) of the EL-34 to the lug labeled
CLAR on the VFO Figure 7. The EL-34 runs in series with the CLAR wire.
