Maybe they know you won't find a 6H5? Usually cross references suggest 6G5/6U5/6H5/6T5 to be interchangeable. 6E5 would be also but is more sensitive. 6E5 closes with -8 volts AVC. 6U5 needs around -22 volts.

:I see that the 6E5 is listed as a substitute for this tube, but when I look at the 6E5 listing it does not show the 6H5. Is there some particular reason for this? Thanks,Mike
