    Short story:
    I picked up a 1971 Ampeg SVT Blueline two days ago for $600!

    Long story:
    I saw the thread here in talkbass about the amp being posted on cl. I also saw that it was in the Bay Area craigslist. Without any hesitation, I email the guy. Blah blah blah. Didn't think I had a chance to get my hands on it and two hours later I get a call from the guy saying that he would be able to meet the next day.

    I pull up to the studio and lets say its not the safest of neighborhoods.. ha. Anyways, I brought my cab (410 HLF) and bass ('08 Fender Precision) with me and headed into the studio. I have never seen a vintage Ampeg head before... Even with all the ranting and raving here on talkbass. I just had to see it!! So I plugged it in!

    I notice right away there is major hum microphonic issues. I play around for a bit. Talked to the guy about tubes and whatnot... I end up buying it. I couldn't turn it down at that price!

    I bring it back to my place where I am on Operation Clean-up! This thing has not been cleaned in who knows how long. Also, every power tube and a couple driver tubes are not fully in their sockets. I replace the v1 tube in the driver section with a JJ 12AUX7 because it wasn't glowing like the rest and I figured it could have attributed to the awful noises I was hearing. Three hours of straight cleaning with a couple lbs of compressed nitrogen, 5 rags, 24 q-tips, I am DONE!

    I then plug the SVT in and... no hum and no noise! It sounds amazing! There are still a couple things I need to replace like some shockmount feet and new knobs.

    I am super stoked with the outcome and I thought I would share with everyone. Here are some pics!

    Sorry I don't know how to upload. Here is the link!

    Great find, well done, doesn't look like it's done too much work either. V1 should be a 12DW7, V2 is the only 12AX7 that should be in the amp. Did you have a 12AX7 in there already?.

    No, it was a 12DW7 but it wasn't looking like it was working right. I put a 12AX7 in there for the time being and it's working great.

    it's a beauty. congrats.
    IMO, for $600 you stole that thing. (paid about 1/3 of what it's worth)
    it looks pretty vigin-ish.
     
  12. That is so awesome!! Freaking score!!

    Two things:

    Does restoring the amp make it lose value?

    If I choose to restore the amp, should I keep the original pieces?
     
  17. Since you bought it for $600, I don't think there's anything you could do to that amp that would prevent you from 'cutting even' if you were to sell it (except maybe chainsaw it in half :p).

    If you could throw some matching knobs on it, re-tolex it, and find an original nameplate from the era, you could actually increase its value.

    And yes, keep the original pieces.

    IMO, that head doesn't need restoration.
