Randall RG-300 Amp how to find production year

[simonb]

Hi Vintage Amp experts

I am the happy owner of a Randall RG-300 top and R-4125 bottom from the 70'ies. I am trying to figure out the production year of the amp to establish it's age.
Any one got an idea on how/where to read/find this information.
Thank for you assistance.

Regards
Simon

Send the serial numbers of the devices to the manufacturer and ask.

Have you pulled out the chassis from the enclosure cabinet? There is usually an inspection sticker on the side or somewhere(hopefully) that has the year it was made. Trying to contact the current "Randall" may prove to be a dead end... They are not really the same company that built that amp.

It's from the 70'ies

No need to dig further .
