Hallo from Germany,
first of all please excuse my English... I'm asking for your help dating the JBL speakers in a vintage Fender Pro Reverb guitar amp. The amp is supposed to be manufactured in 1968. I am not quite sure, if it is in original condition. The built in speakers are a pair of D120F 092577-A, one of them with a stamped in serial no. "19987" (I will try posting a picture). Is anyone of you familiar with that and can help me to find out the speakers' date of birth?
Thanks a lot, Alex
