The JJ 5AR4 was purchased from Antique Electronics Supply. It is a new one and was $15 - not costly. I don't go for boutique rectifier tubes by specific manufacturers. I also have an old JJ 5AR4 powering my Dynaco ST-70 amp and it does a fine job. In this application it will likely be coasting. $15 does seem high but I have to remember that due to inflation the cost of tubes, like everything else, has gone up X10 since the early 1970s. Such is life.
