Title: Supro Super - serial number tag
Post by: theundeadelvis on December 04, 2010, 09:49:06 pm

Hey guys, I'm working on a Supro Super and noticed this little number tag. I was just curious if this is the serial number, and if the date can be determined from it? For no reason other than to satisfy my curiosity. Here's a picture:

I don't see any numbers on the speaker, but I can't see the top edge. I'll have to pull the chassis.

Check the codes on the pots, filter caps, transformers and speaker. Judging by the serial number I'd say it's a '67 or '68.

Numbers are likely on the side of the magnet :smiley:
