    Just aquired a fantastic shape vintage AMPEG SVT Blueline. Curious as to what year the experts think this amp is? Here are some other interesting features:

    - GE6550 USA Power Tubes
    - GE Tubes in the lower chassis as well.
    - Appears like the preamp tubes are a combination of old tubes (havent taken them out yet to fully confirm)
    - Two prong power
    - All the weird screw heads
    - an original, "hard wired" speaker cable. Aparently was only changed the end from 4 prong to 1/4"
    - Unique band logo on top "Rockestra"
    - Both transformers appear original, one has "Hammond" on it. saw a similar example on ebay with same part numbers
    - fan updated
    - original tolex, etc.

    In any event, very quite at idle, with a hint of occasional microphonic ring when turned up. Sounds amazing when running full!!!! Worth it.

    Also in pic is my stock 1961 Navy Flair Ampeg B15 to match for a heavenly combo.

    Any input greatly appreciated!!!

    At the age that yours is, you'll need to look at the serial numbers, notice that I said numbers, pots, transformers etc. for a better idea. So many things get changed, hard to tell just from the exterior. Very early ones had only 2 power cord wraps for example. However, like most makers, consistency is not always consistent. Just be careful inside. Very lethal voltages if the wrong things are touched. As I heard one guy say, "It'll kill you 'till you're dead."

    Got a 74' with matching 8x10 cab. Yup, worth the weight. And yes, I hear the " lighter amp is still the same" line from all the mark bass and genzbenz guys.....NOPE. NOT the same tone. And yes, its' STILL worth it to carry the fridge with its' head around ( I do a lot of gigs). Older Trace and some of the Ashdown S.S. heads do sound smooth, though.

    this should be in the amps forum, not basses. Cool amp though!
