Thanks for the clarifying illustrations. Before going on, I'd better
state my assumption that L1-C1-L2-C2 is the simplified model
of the transmission line, so we don't get any misunderstandings
Yes, I agree that Fig. 2 is highly undesirable. I might perhaps
have caused a bit of confusion with some of my earlier posts,
since I use an extra resistor in parallel with the phono amp input,
to bring down the load impedance. It was this resistor I was
considering if it would better be on the TT side of the cable. In
my case I think not, since it is of much lower value than the
amp input impedance, getting us closer to the case in Fig 2.
Good that you brought RFI into the discussion, since we had
missed that parameter entirely. But then, if we have a choice,
wouldn't it be best to terminate with a low resistance at both
ends of the cable. Or would the coil serve that purpose despite
its inductance? What about Zobel filters at each end, as Rod
Elliott suggests for other parts of the sound chain?
Sorry Jocko, but HF and transmission lines is absolutely not a
strong side of mine, so please forgive me if I mess things up

Probably would not be much harm in terminating at both ends. If you split the load up, i. e., doubled the resistor values.

I hope it's not the "making yr. own cartridge" part?
Was I backing out of something,somewhere?

thank you very much, i said so already in the post removed by a fellow moderator.
Your pixes make perfect sense.
