Gambling?

Am planning to use an old FC-1000 automatic antenna tuner and a new FT-450DM tranceiver. The technical staff of the manufacturer told me that it was possible in theory if I prepared a connecting cable by myself, but I should do it at my own risk, as they had not tested the combination. Apparently, the company's policy is to sell the new tuner, FC-40, at about \50,000.
In the photo, the the left side of the cable goes to the linear amplifier terminal of the tranceiver and the right side goes to the controller unit of the tuner. Three RCA plugs and a Molex connector were removed from the cable that was connecting my old FT-757 and the controller. The FT-757 went out of order in January and could not be repaired due to the lack of parts.
It was cumbersome to match nine wires of differnt colors and connect them by soldering.



長年使っていたFT-757が故障して修理不能なので、代わりにFT-450DMを買いました。オートチューナーのFC-1000はまだ壊れておらず、もったいないので、接続ケーブルの工作をして、使ってみたいと思っています。メーカーのサービスは、線をちゃんと繋げば使えるはずだが、動作の確認はしておらず、自己責任でやってください、とのことでした。さて、結果はどうでしょうか？

早く免許の手続きをしないといけませんが、週末にかけて予定があってすぐにかかれません。
