Testing 1C7G on TC-03 Heathkit Tube Tester

I would like to test a 1C7G on my Heathkit TC-03 tube tester. Although settings are not shown on the chart, could someone suggest what the test settings should be?

Does the chart show a 1D7 or 1D7G?

Unfortunately, no.

I have a supplemental test data sheet for a Heath TC-1, TC-2, and TC-2P dated 1/1/64. And based comparison of data for the TC-3, all the settings are the same as the TC-1/TC-2, except that the plate settings are about 5-15% lower for the TC-3.

1C7 setup for TC-1/TC-2:

Test 1: Type 2, fil 2, plate 41, top EF, bottom G

Test 2: Type 1, fil 2, plate 56, top CDK, bottom G

I forget - maybe it was with the TC-2 when I got it.

They used to be on the Bama website - but they may have been pulled due to a legal controversy.

Here's a partial one for the TC-3.
