A sad day yesterday. I returned the amp to Guitar Center (where I got it). Lucky for me when I bought it - it wasn't labeled "vintage" (because of the changed out baffle and speaker) so I had 45 days to return. When I got to GC and wheeled it in a customer who is a "regular" there remembers...

I liked at the '67 manual that beans on toast attached and the picture of the '67 looks nothing like mine. It seems a model change took place. But with the production of the transformer being almost last week '66 and my serial number (which I found finally) (056560) it seems this amp dates to...

Thanks for the support! I rolled it into the studio today! In my quiet studio it's even more ballsy. I noticed like a buzz at idle with volume down coming from the power tubes so not sure if this is normal or an adjustment or amp tech visit is needed. Didn't notice it in the noisy...

Totally agree Ric. Thx. I'll get into it and see if the baffle can accept an originally sized speaker. Any other ideas besides the Eminence Beta 12A? I guess in a perfect world I would want a replacement speaker to handle the low notes of my bass (not at a loud volume but reasonable) and...

Thx coreyfyfe. If the tube cage is the big metal mesh basket that sits on top of the amp and screws in then yes (and protects me from hot tubes:)). It has the plexiglass decorative A Ampeg logo as well. And yes to the 3 prong modification. What's the reason to correct that? Hard wire it in...

I looked closely at transformers and their numbers indicate 682 651 and 682 639. Based on an SVT document I read this means the Electrical Windings Company (682) and the 51st and 39th week of production in the year 1966. SO would it be a safe bet to assume this is a 1967 amp?

Thanks for replies. Can anybody tell me what's not original in the circuit? Any comments about whether transformers are original? Tubes? I almost subscribe to the idea that "if it sounds good, get it". But it would be nice to know what this really is in case I go belly up and have to sell...

Yes so the seller says it is a 1965. They want $700. I took some photos. I'm going to try and see from the codes from the transformers what year it truly is. I looked everywhere and could not find a serial number. I played it a bunch today and it is almost useless on bass because whatever...

Hi - New here. So 1st post. I've been a bass player for about 10 years and currently record in my studio with the Reddi DI but when I heard this amp I wanted to start micing it up. I was wondering if anyone can tell me specially how to authenticate the transformers, tubes and circuit for this...
