For sale is this Job Lot of 10 x Large valves of different types and from different manufacturers, some have their markings missing but there are at least 2 x PL504 and 1 x PY800, along with several others. Many appear to be output valves. There is also a top cap socket with wire included (see photos). I am unable to test these valves so they are sold as seen and I cannot accept returns. This is reflected in the price.
