ADA Flanger Serial No.

[ambulancevoice]

Hey!!

i recently purchased an ADA flanger, it has the MN3010 inside and a power adapter (not the inbuilt power supply) from pedaldoctor.com
now, it has a serial no. on the bottom and i wanted to find out what year it was potentially made, as the seller said its a late seventies model

from what i understand, the first model had the SAD1024, then in 78 they switched to the MN3010 with a wall wart, then in the 80s it was released with an inbuilt power supply

ive done some searching but cant figure out how to read the serial no.

the no. is 227318

cheers guys!
