70s Fender Super Reverb dating question

I apologize if this has been covered but I searched and couldn't find the specific answer I'm looking for.
I'm buying a 70's SR from a local shop (just put money down to hold last night:)
It's a silverface and has the less desirable master volume but I maxed it and used the channel volume and it sounded fantastic to me and is exactly what I'm looking for in a pedal platform.

It's listed at the shop as a '77 which I thought was the year they went to the "ultralinear" model.

This one is 45w. I've found contradicting serial number info online, basically this site (http://www.ggjaguar.com/fendamp6.htm) states that a SN of A7..... was built in 1977 but further down the page when broken down by model it specifically shows my SN of A737703 corresponding to 1974. I know silverface dating info is hit or miss but can anyone clarify for me? Doesn't really matter as I love the sound either way but it would be nice to know its birth year;)
Thanks

I always felt SF sound was unfairly trounced vs BF sound. SF sound has it own excellent clean sound - IMO better than BF.

Condensing OP - just wondering if anyone can verify that serial number A737703 is in fact a '74.

Go with the amp specific serial number info. Puts it at 74. To be more confident, pictures of transformer numbers or the little white tag on the speaker rim, if intact.

Cool, thank you. It's not in my possession yet but I'll check trannies and speaker codes.

While SF vs BF is quite overblown in terms of sound and utility, you do want to make sure you know the watts/ultralinear- that does make a big difference.

Ultralinear models are 70 watts, right? This one is 45 watts and I'm pretty confident (especially after the last couple of posts) that it's a '74 which would put it several years before the UL models.

A737703...this serial number format was adopted in 1977.....A plus six digits will give you the year. The ''A" indicates the '70's, the first digit indicates the year.....this amp was built in 1977. Your transformer codes, pot codes, etc will support this. since this amp is not an Ultralinear, I would think that date codes will indicate that it is a very early 1977 amp....perhaps with some 1976 production date codes on trannies, pots, etc.
Whoever is dating this amp to 1974 is ignoring the six digits there. If this serial number had an A followed by only 5 digits, then yes the number would be good for circa 1974.

Damn, I think you're right. I just checked that site again..I guess I didn't look closely enough at this part:

Super Reverb AB763, AB568, AA1069, AA270 (silverface)

A26000 to A29000 – 1967

A29000 to A35000 – 1968

A35000 to A45000 – 1969

A45000 to A49000 – 1970

A49000 to A54000 – 1971

A54000 to A58000 – 1972

A58000 to A66000 – 1973

A66000 to A76000 – 1974

A76000 to A79000 – 1975

A79000 to A80000 – 1976



Didn't realize there were only five numbers after the A... Okay I feel dumb now. Thanks for pointing out what I missed. :facepalm

That's a BF inside. DR didn't change the guts until later. So really not a SF sound. However I agree, there is very little difference in many SF vs BF. Some are oddball though.
I'm learning everyday! Great sound this guy had (I think he sold it).

The codes will tell the tale. The S/N were gathered by comparing transformer and pot codes to serial numbers. None of them are definitive on their own because Fender just grabbed parts from the pile and one part could end up lying around for a year or two, but not all of them. Get back to us with the codes. The speakers, as much more easily replaced, are less reliable...

I see the hum balance control on back. I may be wrong, but wasn't that introduced when they went Ultralinear?
