Thanks for the reply Tom. My 3RP1 specimen has 12 pins, while the 3RP1A has only 10. Any yes, flat face on the "A" version versus the curved on the 3RP1.

>The question: will a 3RP1A replace a 3RP1 in a HO10 monitor scope? The "A" version has 2 less pins than the standard 3RP1. Meanwhile, they are being advertised "bayside" as being interchangeable. It appears that the 3RP1A will plug into the tube socket just fine, but there are wires attached to the sockets where the pins on the "A" version are missing. Thought I'd ask before I smoke it. Thanks is advance for sharing your greater knowledge and experience. 73
