I pulled this information from Google's cache of the site. If anyone feels this page should be taken down, please feel free to contact me. Ampegs can be divided into six distinct groups for purposes: pre, to mid, ampeg cabinet dating tototoand post Each group uses a unique serialization scheme that can be used to assist in dating the amps, but in many ampef, it is the features and characteristics of the amps that determine the year of manufacture.

Electronic Industries Association EIA codes can also be very useful for giving clues as to ampeg cabinet dating amp's age. These codes can be found on speakers, transformers, pots, capacitors, and multi-section electrolytic "can" caps. Of course, these codes are only applicable to original components, not replacement parts. Shortly after World War Cabbinet, American electronic component manufacturers began to stamp a semi-standardized code into parts they produced.

The code contained information regarding the manufacture and date of production. These codes have been used on components including potentiometers potstransformers, capacitors, tubes, and speakers. The code usually consists of 6 or 7 digits such as where the first two or three digits is the EIA code for the manufacturer denotes CTSthe fourth digit and sometimes fifth digit denotes the ampeg cabinet dating in this case it could be cabibet, 66, or 76and the last two digits click the following article the week of the ampeg cabinet dating.

It is important to note that parts do not always contain EIA codes, especially those parts from the late s and early s. The Ampegs made between and did not have serial numbers and must be dated in the same way as the Michael-Hull models, specifically, by finding the EIA date codes on pots, transformers, multi-section "can" capacitors, and speakers.

For example, a Duette with serial number was made in 7during October 10and was possibly the st amp made that month.

A Super Echo Twin with serial number was made in 4during April 04 and may have been the th amp made that month Caution is needed for dating amps from this web page,, and Ampet serial numbers from these years were duplicated inlink,andrespectively. Taking the example Super Echo Twin above, its serial number alone could denote April or April A Mercury with serial number could be from September or it could be from the second serial number system implemented in Luckily, it is very easy to determine which year the first digit denotes.

The key ampeg cabinet dating the model and the cosmetics. For instance, the Super Echo Twin was made inbut not in Likewise, an Ampeg from would not be covered in blue check vinyl whereas an amp from would click this covering. An Ampeg from would be covered in navy random flair vinyl whereas an amp from would be covered in blue check vinyl.

Another check for a versus a or later serial number i. Datnig, a serial number where these two digits are greater than 12 must be from the second serial number system - A final cross check with EIA dated components should cahinet any doubt about an made during the - 65 period. The second dating site starters number system was implemented in January and used until the end of This system overlapped with the source serialization scheme for a period of about 6 months.

These are also 6-digit numbers, which appear to have been applied sequentially, but they are not cainet encoded. Enough information serial numbers, model, date codes has been gathered to prepare the following guide for dating by serial number.

Note that the associated with a range of serial numbers is very rough site for dying will likely change as more information is gathered for refining the estimates.

The EIA date codes of original components should be used to confirm an approximate date of manufacture. The third serial number system was implemented in Not enough information was available to the authors to determine year of manufacture by serial number. Cbinet added variable is that during the Magnavox years, Ampeg may have used separate serial number systems for each model or for models that shared the same chassis like the VT and V Until such time that enough information is available to date s Ampegs by serial number, the features of the amps from this period can be used and compared to the following table.

Ampeg V4. Therefore, do not poke around in your old Ampeg if you are unfamiliar with amplifier electronics or their operation.
