Marshall Amp Forum - View Single Post - Would this mod work on my 1960A in stereo?

Man-Machine · 10-30-2008, 06:52 AM

I'd like to be able to go back and forth between two types of speakers (the stock G12T-75 and some Vintage 30 speakers) in my 1960A cabinet. I want to just swap the speaker cable in the stereo mode jacks to hear each pair of speakers. Is this possible? If so, this is what I gathered so far. Please, correct me if I'm wrong or missing anything. I'm new to all this and I don't want to blow out my new JCM800!

*For this to work I'll need to arrange the speakers in columns, not in an X pattern.

*I can do a straight speaker swap as long as I match ohms.

*I'll need to change my JCM800 to 8 ohms output for the stereo mode of the cabinet.

*I should be ok pluggin into two 60 Watts V30s with my 100W JCM800

Thanks for any help!
