How old is the ampeg reverborocket i'm looking at?

[sidehatch]

the model is R12-R
serial number is 004634

Its in excellent to mint condition.

if anyone can tell me the date an a possible value I'd appreciate it.Its a friends who needs money and I love the way it sounds. If its more than I can afford I'd still like to tell him the year so he can sell it.

Thanks for all you guys help!

See if you can find the EIA codes on the transformers. This would be a 6 or 7 digit number.

For a 7 digit number, the first 3 are generally the maker, the 4th and 5th digits are the year and the last two are the week of manufacture.

For a 6 digit number first 3 are still the maker, the 4th digit is the year, and the last 2 are the week. You know the decade from context. This amp likely dates from the 60's but I couldn't say as I'm not an Ampeg expert.

Post the code if you find them. Someone is likely to confirm the year for you.

There are also numbers on the pots, and they can also be used to date the amp.

these are the codes I have found

PT-100

862 443

OT 151

Do you think this is a 64?

Earliest ones 63(?) used 6V6s and octal preamp tubes.

64-65 used 7591s and octal preamp tubes.

Above had top mounted chassis like a tweed fender.

Later Reverberockets had front panel controls, miniature preamp tubes, some with compactrons.
