Welcome to the forum,
If you search "Serial Number" in the forum search engine the first hit gives a pretty good run down of the serial number schema...but the serial number itself is not much help.
To get the date of manufacture is difficult, but you can narrow it down to a few months using the manufacturers date code on the transformers...google woodward-Schumacher Transformer EIA (Electronics Industry Association) codes for the schema...but it is something like
606-XYY
X is the year of the decade built, for example 1977 will be X=7
YY is the week of the year, so YY will run from 01 up to 52
Speakers have a similar EIA code as do potentiometers and older tubes of this era.
There is some cool old catalogues etc. in the " Downloads and Resources" area of the forum website.
Anyone seen or have a Serial as old or older the BN00539
I am sure they are out there I have just never seen one. Had the amp since roughly end of 74 to beginning 75 as memory services me and have had it ever since. Still in great condition speakers have long be replaced but that is the only things. I will check the dates on the electronics but does not hurt to ask.
Any inform would be great and thanks for the add.
Mine is a chassis that I ended up with while working at a music store and it got stolen, Long story, Ended up being returned to me. Was a 12ax7a version and I converted it to SS driver and didn't like it. Went BACK to the tube driver, had a couple of problems and while getting the hum out, dropped a pair of pliars in it while hot. Never DID get back to fixing it. Who NEEDS 130 watts! Mike.
Hi there ,, I have bass stack in eksellent shape amp is HD130 without reverb/tremolo and serial number is A002002 ? can it be early as faak ? wishes Jarkki from Finland
Best way to know is open it up and look around. You MAY find a date written on the driver board or the main board or even scribbled on the inside of the chassis.
