I am looking a a couple L3 Unfilmed WP tubes and am wondering which one to go with, tube one is cleaner with a much lower EBI, while tube 2 has higher specs (SNR/FOM) but has a small blemish. Which would you choose?
Tube 1:
Photocathode Sensitivity 2856k - 2193
EBI - 0.3
SNR - 31.3
Resolution - 72
Halo - 0.8
FOM - 2254
very clean, zero blemishes.
Tube 2:
Photocathode Sensitivity 2856k - 2545
EBI - 1.1
SNR - 34.7
Resolution - 72
Halo - 0.7
FOM - 2498
Very small blemish in Zone 1.
