    When did 4 bolt necks start and stop with Fender Jazz basses?

    Bassman 135 speaker inputs

    Steve. I know it is an old thread but could you confirm you could then have a pair of 8 ohm cabs in parallel plugged into the EXT jack making 4 ohms and have the same setup as described in your last paragraph above plugged in too? Kind regards, J

    Old Fender Bassman 100 speaker outputs - how do they work?

    Cool. I have learnt that the mains trans has been changed to a Hammond from a Schumacher. I too have also learnt that the original 100 OT did not have multiple taps. So, I need to know if the OT is original or not. Is that diagram for the Bassman 135? Were the taps on the 135 auto switching or...

    Old Fender Bassman 100 speaker outputs - how do they work?

    So, shop manager went home. Will know something tomorrow. We know the previous owner has had some work done on the amp. I am of the opinion that the previous owner desired the tap setting on the Output transformer be changed. My question is, is it a simple case of having the tap setting changed...

    Shop manager is looking into this as we speak. I'm not sure if the panel is related to the OT or another part of the electronics.

    Starting to look like the OT might be an 8 ohm unit or setup that way, and the Total load 8 ohms label has been expertly painted on or something like that.

    So, would this transformer be an 8 or 4 ohm unit? Or does it matter how they are wired up? Your post suggests OT's can be wired to what you want.

    Thanks for the info. Should I disregard the NOT in your sentence above (So it's not usual for...) to make it sensible? No offence Poking around by the manager of the shop is going on at this very moment. Cheers.

    Old Fender Bassman 100 speaker outputs - how do they work?

    Both pics are of Bassman 100's for sale on the net. You can just make out the Model numbers. The 8 ohm pic of the Bassman 100 in question, I have other pics of. It is for sale from a business and the manager is now as confused as me. It has had many parts replaced but that doesn't explain the...
