29 Sylvania JAN 5814A 12AU7 Tested Vacuum Tubes - GONE TO WELL-KNOWN AUCTION SITE

For sale is for a group of twenty-nine Sylvania JAN-5814A vacuum tubes.  While the printing is worn off of many, these appear to be late 1970s grey plate versions, and all are identical in construction.

I tested these on my recently repaired and calibrated RCA WT-110A tube tester.  This tester is very reliable, and tests for shorts/leakage and gas, but unfortunately only gives qualitative results for transconductance.  I have reported the transconductance results as an approximation (to the nearest 0.25) of the meter reading.  The meter goes from 0 (low) to 10 (high), with the green ("GOOD") at 5.5 or greater, yellow ("?") between 4.5 and 5.5, and red ("RENEW") below 4.5.  10+ is off scale high.  I do not know what meter reading 100% is intended to be, but experience tells me it is typically around the 7-7.5 range.

The results are as follows.

#1   6.25/6.5
#2   9.5/10
#3   9.75/10+
#4   7/7
#5   8/8.5
#6   6.75/8.25
#7   9.5/10
#8   10/10+
#9   9/10
#10   7.5/7.25
#11   10+/9
#12   7.75/6.75
#13   9/7.5
#14   6/6
#15   9.5/10
#16   9/8.75
#17   9/9.25
#18   9.5/8.75
#19   7.75/6.5
#20   7/5.75
#21   6/6.5
#22   10/9.5
#23   9.25/10
#24   6.5/9
#25   6.5/6
#26   7/8
#27   8.25/5.5
#28   9.25/8.5
#29   8.5/7.5

All were clean for shorts/leakage/gas.
