We even sold 40 Ref9 to an Israel company for ultrasonic use in fault detection. John Casler sold the first pair at midnight in a Los Angeles carpark to two engineers who were separately hunting for lightweight and compact ultrasonic amp, lol.
LOL. . .yes that was a funny story.
These guys called me and ask if I had the amps. They said they were working on a Top Secret Israeli Military Project and one of them was an Israeli Secret Service Agent. It all sounded strange, yet my curiosity got the best of me.
It was on a weekend, late at night. They said they needed these specific qualities to send sonic signals through the hydraulic systems of Military Devices like jets and ships. They said with the right amps and their equipment, they could find leaks, and faults, and "predict" system failures, with something similar to ultrasound or ultrasonic sweeps.
I agreed to meet with them in my underground parking garage in Century City.
They showed up around midnight in a Big Blacked Out SUV and called me to come down.
I told them I could only do this on a CASH basis. It took them a couple hours to visit ATMs and between the 3 of them they had the cash (in $20's)
I went down, they examined the amps (they really only wanted one, but I told them I had to sell them as a pair)
They handed me a big envelope full of $20 bills and there we were counting 20's as my neighbors drove in and out, likely thinking I was a drug dealer. . . .LOL
But as Jason said, it all worked out, and they placed a larger order after making sure the system functioned as expected
