hi everyone iv got these two spare p8079hp iit tubes for sale, both home built devices have focasable objective lens with adjustable iris.. both have very good gain. and i havent really used them much, i bought three but soon realised i could only use one at a time! so three of them is excessive, so they need new homes (preferebly in the uk i am after 445nm 1watt or 2watt diodes and drivers and hosts, i will consider any response.. these tubes are decent tubes!!
