1. Welcome to TalkBass 2014! If you're new here, we just went through a major site upgrade. Please make yourself at home! I've deleted the previous "migration" threads, please post all concerns and bugs to the Forum Usage Issues forum. We will be monitoring that forum.

    The TalkBass iphone/android app is NOT WORKING currently. We're working on it. Tapatalk IS working, so if you need to use an app, use Tapatalk. Try using your browser though - TalkBass is now 100% responsive to your phone/tablet screen size ;)

    Please read the TalkBass 2014 FAQ for lots of great info on the new software.

When was this SVT 3 pro made.

    A friend of mine just picked up an SVT 3 pro, that basically looks like it is brand new, and asked me to see if I could see when it was made. Its a Made in USA model Serial Number is 2560B. From doing a bit of research, it seems it is an 89 model, but like I said this thing looks brand new, not at all like a 25 year old amp.

    That is not a valid serial number.

    I was thinking it didn't seem to add up with the information I was getting online. But that is the only Serial Number on the amp.

    First I've ever seen a serial like that. Leads me to believe it's a very early one. What does the front look like?

    If you dare to open it up, you might see date codes on some of the components such as the pots. Capacitor cans mounted on the top of the chassis often have a date code stamped onto them. These date can help you estimate when the amp was made.

    Lol, I'm sure there's nothing under the sticker. I'm the original owner, bought it in 94.
    Serial # says it was built in 93, the caps have 9303 stamped on them, I assume that's third month of 93 but I could be wrong.

    Hmmm...that looks like a newer one...well maybe Jerrold can shed some light on the serial number discrepancy when he comes on. Too new to be a prototype ;) Very strange...

    Strange, I wonder if there was once a sticker over what is there now.

    Yep, mine is even an older style than FC Bass' amp.
    On the first generation the "tube gain" knob was labeled "plate voltage"
    Your buddies amp is relatively new, looks like a 2000's amp to my eyes

    I've owned 2 of these. Both of the fans had manufacture dates on them that lined up with the year, from the unit S/N's. Shine a light, through back side resistor vent, and see if you can make out the numbers on the fan.

    A closer look at the Plate Voltage control.

    The standard serial number deal goes back to 1988. So the label is missing. It has an ETL sticker, so it went through the normal processes.... and had a serial at one time.

    We did have, sometimes, people sneak enough parts and reject PWBs out to build and sell an amp. Those had no serial, and usually had "dunker" PWBS, ones that had scooped up some solder on top when they were wave soldered.

    They can be spotted by traces of solder still sticking to the topside of the PWBs. I doubt this is one, but it is possible.
