My Plush amps/cabs serial number is nnnnnnn; what year was my amp/cabinet made?
This is a tough one, and short of various inspection stickers, and reliable transformer codes and pot codes, there is currently no definitively reliable way to determine an accurate date based on serial numbers alone. Pretty much it seems that Plush existed for a period from 1968 to 1972 (or so) so that would pretty much be a good start. From there, you can get a better idea by using the numbers found on the potentiometers in the amplifiers. These are great for dating the *earliest* the amp could have been made as the amplifier could not have been made before the components in it (barring replacement bits). I have seen date code ranges of 2 years in some of the amplifiers that I have looked at. These eras and their approximate and relative date ranges are as follows: – 1000 and 1060 series. These were made during Plush’s entire existence so these are the hardest to date. – 3000 and 4000 Series amplifiers. They only show up in the 1971 catalog, I haven’t dug through enough of these to f
