Mike, thank you for the clarification. Jack it turns out has been on vacation and not have ever seen this in all the posts. Just a few more parts to get ordered and then sit on my hands for a couple weeks for all the parts to show up!
Jack, quick question, I'm currently sourcing parts for the PKAA project. It appears the?MSA-0386 op amp is no longer readily available and that you referred to substituting it with a?MAR-3SM+ in the assembly manual. I see lots of?MAR-3SM listed on eBay but not?MAR-3SM+. Is a?MAR-3SM and a?MAR-3SM+ interchangable?

Second, do you have a link to the source you used for the box you put the PKAA in?
