First I have to apologize for giving you bad info over the weekend. Even
though you clearly said "phono" I had "phone" in my mind and thought the 2
jacks in question were something like on the 430, a 1/4 for key and a 1/8
for external speaker. never having owned a TS-50, I took a shot, and
missed by a mile.
Knowing what you know now, you have to decide if you really want or need
the buffer. The rig seems to be set up for direct connection to the amp
via a pair of rca cables. Maybe you would want to sell the buffer and
cable and recoup some of your money, or keep and use it for some margin of
protection.
I just took a fast look at the manual for the buffer. Since there seems to
be no place to plug in the pnp cable, you wouldn't use it. You would
connect the keying line from the rig to the jack marked "radio" on the back
of the buffer. When looking at the rear of the buffer, it is the third from
the left, right next to the 5 pin din jack. So your key line goes from
the rig to the jack marked "radio" and then a cable from the jack marked
"amp" to the keying jack on the amplifier. The "amp" jack on the rear of
the buffer is the first one on the left when looking at the rear. The
middle jack is "alc" but you wouldn't use that one as you would connect
direct from alc on the radio to alc on the amplifier.
Since you would not use the pnp cable, you will need to provide some
source of external 12 vdc for the buffer.
Yeah, some of it doesn't seem to make sense, but I guess that's why they
call it amateur radio.
