Nice new 4/5 pin sockets for British tube types such as PX25, PX4, ML4, AC-P etc, with high-temperature rated plastic ABS body and phosphor bronze contacts for good tight contact with valve pins. (Note that both 4 and 5 pin - B4 and B5 based - British valves use the same socket, the 4 pin ones just don't use the center pin) These are new production items made in Britain. |
