This is high quality PCB diameter 19mm with soldered high impedance voltage divider for Photomultiplier PMT tube. The PCB pinout will fit Hamamatsu R1213, R1450 etc. tubes. The PCB is also can be wired to any PMT with up to 10 dynodes, use short wires and mini molex female pins for that purpose (molex pins are not included in that ebay listing).

The PCB is perfectly fit DIY PMT projects where you need to wire high impedance voltage divider to your tube. I include pinout of R1450 as a reference example, see product photos!
The action is for one (1pcs) of the PCB with soldered resistors for R1450 tube. 

If for some reason you need different total resistance please contact me to ask in advance.
