I just bought a TP-117 without the remote. I'm attempting to program a univeral remote to control it.
If you have the remote, I would like to use a smart univeral to copy its code.
If you do not have the remote, and need the code, I will be happy to share mine with you when I develop it.
I don't have the TP-117 manual, but I understand the unit will control other specially built Luxman components via DIN cables. The DIN cables can be reproduced.
The TP-117 has the legendary T-117 tuner and originally cost $1,280. I believe it is worth the trouble of getting it to work.
