Default testing 8417's on mercury 1000

I have a mercury 1000 that does not have tube data for 8417's.

since the Mercury 1100A, 1100B, and 1100C use the same settings for testing 8417's as used for kt-88/6550/etc, I tested using kt-88 settings and just raised the load til I got the correct transconductance.

Anyone have updated tube data for a Mercury 1000 that includes 8417?

thanks

You did it right. Now you have the data, and should share it with other owners of that machine.

confirmed.

just found out that the tube chart for a Mercury 2000 is good on a mercury 1000.

The only difference between a 2000 and a 1000 is a transister tester.

In the Mercury 2000 tube chart i have, the load is blacked out and hand changed to 50. I was using 45 thru guestimation.
