I have the yaesu 101 twins, FR101s receiver and FL101 transmitter. Transmitter uses the stock 6JS6C tubes. The 6HF5 tubes can be made to use in it, with slight change on tube sockets (look up specs). These tubes can be gotten from 15 to 20 bucks, much cheaper than the stock tubes and have almost the same output. My FL101 was made to be able to use these tubes or the stock ones. I just purchased another pair of the 6HF5's at a hamfest locally for 15 bucks each, good old GE stock, and work great. I wanted to have some spares because we all see tubes are getting scarce. Hope this helps.
