Interesting that nailing the values for R2A and R2B is so important. Seeing that Mouser has the exact values desired and delivers super-fast makes using them a lot easier. Granted that puts the build cost near $100 instead of $70, but $100 is still quite a bargain for an attenuator that works so well!
Thanks for that. Good reminder, I've ordered from Mouser before. I'll have a look at their pricing. It may be worth it for that one value as I need to order some other parts as well for other projects.
