My CR70 has no settings listed for this CRT. I tested as a 7JP4 and it did test very strong.
Were there any circuit modifications to the 8" sets? (vs the 7" sets)
Thank you.

The 8BP4 8 inch electrostatic tube is electrically identical to the 7JP4. You can plug it into any working set that uses the 7JP4 for testing. My Motorola 9VT1 uses the 8 inch tube and the same TS-18 chassis is used in the 7 inch model without circuit modifications.
