Here is a brief listing of the manufacturers Source Code numbers: 34 – Cornell-Dubilier Electronics (made capacitors used on early Fender Guitars and are the ones that were paper and wax coated.

Fender used two kinds of silver/blue grill cloth, first version, as with your amp, the blue stripe fades away to red, then brown and eventually disappears.If a component manufacturer is unable to use the four (4) digit code date, an alternate three-digit (3) code may be used by taking only the last digit of the year.Then 134-6320 would become 134-320 and the specifications of the instrument should be used for determining the approximate year or decade the particular instrument was built.I use this before buying a amp always-check all four transformers-will tell you if there has been problems along the way. On the bottom lower corner of the grill cloth was/is a 1×2 inch “JBL” plastic logo that Fender attached.By 1968 deluxes usually left with CTS/EMINANCE speakers (Jensen had closed down) Once in awhile you can see the EIA code, CTS-starts with a #137-sometimes these are under the doughnut fender speaker label.
