Serial Number - How Do I Find My Product's Serial Number? All of our products are labeled with a serial number. The serial number will be printed on the product itself and will not be anywhere on the packaging or box. Do not have serial numbers. Please check both of the inner earcups under the earpads to find the serial number. I have the serial numbers on the speakers and, from what I’ve been able to gather, they look to be from around the same time as the amp (1965). Unfortunately the pics do not really include the cone (so I can’t see any stamp on the cone). The frames are gray with yellow JBL on the driver. Serials are 117xx and 120xx (where “xx” is a number).
