I am looking to rehab an old Apollo 300X base amplifier to use with a MFJ-9406 on 6 meters.  It uses a single 6LQ6 in GG and has an output tank circuit for 15, 10 or 6 meters.  I need a schematic for it.  It does not have a tuned input so I will need to add one, get rid of the COR and replace it with a keying line and make sure that it is biased correctly.  Should be a fun project and I have several NOS 6LQ6's in the tube stash so that will not be an issue.

Thanks,
Randy AB9GO
