Cossor V9
Hi all,
I have to admit I am stumped. can anyone tell me the difference between a cossor V9 and a PX4? I opened up a box of valves I bought years ago at an auction & found this cossor V9 in a box with handwritten PX4 on the outer cover. The valve tests 100% on my avo valve tester as a PX4 No data either in the avo book or the Mullard valve data book for the V9? All very strange Paul |

Re: Cossor V9
About £300 I would think. The audiophools would want it etched "PX4" in gold.

Re: Cossor V9
It quite likely is a PX4, or 4XP as Cossor marked them: http://www.r-type.org/exhib/aag0017.htm
