Matsushita / PCC88/7DJ8-MATSUSHITAThe Matsushita Corporation of Japan made some very good sounding audio valves. These were so good that American companies such as Raytheon bought the product and put their own name on the valves.
The National brand was owned by the Japanese until a US company bought the name.
These PCC88 are of very good audio quality and have proved very popular with audio customers. They come with the original print in the original National red boxes.
