    Congrats on your score. I'm not a gearhead at all (...where do I plug in, man...) but have had a Concert since the 80s and love it! Hasn't been my main for years but everytime I fire it up it sounds great! Doesn't quit! Loud

    I had one back in the early 70s. If I remember right, they are 150 at8 and 200 at 4ohms. Ok for smaller gigs. No real powerhouse though. I used an Acoustic 370 and 371 bottom for the neck pickup, and the Sunn Concert with 2-15 bottom for the bridge pickup on my stereo wired Rick. Then it had some power. Good Luck

    I also had one the first year they came out,very early 70's.When I got mine it was 150 watts into minimum 4 ohms.I thought mine had good power and great tone,I used it with a Sunn 200s cabinet with JBL D 140s and later a Cerwin Vega B 36 folded horn cabinet.Both these cabinets were 4 ohm.Yours looks just like mine did so it must be a early 70's,later they had a black front panel.The one you have looks like it's new,good job.

    I haven't done any research but going from memory, your amp is probably from the early/mid '70s. I think they ditched the distortion circuit and switched to red tipped knobs mid-late decade.

    Your amp is of the style shown in my '75 Sunn catalog.

    Just looked at your pictures up close...man is that amp clean!!!!

    They aren't tone monsters, but it's a good servicable amp. I used one for a couple years - pushed two JBL 15"s just fine.

    You've got the early model. They lost the full stripe across the front and added 50 more watts around 79. If I remember right they rated them at 150w and 200w @ 2ohms but they are 4ohm min. heads? Ask me how I know.

    This mod was done a bit before 79. My 1977 Sunn Concert Bass (purchased new in 1977) already had this mod (no more stripe across the front + additional power).

    Cheers

    I have the same one (but looks ALOT more road worn) Don't know about the ohms but I run mine through a hardke 4x10 and it sounds great. I've been using mine since I bought it used in the early 1980's. Needed a refurb once about 2 years after I bought it (smoked it). I have repaired a few bad solder joints recently but it is still a good reliable amp.

    I rocked an identical amp for 20 years without a single problem. Times have improved tone, but reliability speaks clearly. IMHO great score for a practice amp
