Hi,

Question about connecting a Model 1982B 4x12 lead cabinet to my Model 4211 JCM800 100 watt lead combo.

I just want to be sure on the ohms before connecting the 1982B. Both have been in storage for over 30 years. I have already tested the 4211 combo and it is working fine, It has 2 x G12T-75's connected to one of the two speaker jacks in parallel, with the ohm dial set to 8 omhs. The Model 1982B lead 4x12 cabinet has 320W RMS and 8 omhs marked on the plate. So the questions are...

1. With the 2x16 ohm combo speakers in parallel the amp should be set to 8 ohms on the dial, correct?

2. If I disconnect the 2 combo speakers and only plug in the 4x12 cabinet, the amp stays at 8 ohms?

3. If I connect bothe cabinets, combo at 8 ohms and 4x12 at 8 ohms, should the amp be set to 4 ohms?

Sorry if this sounds like a dumb question, but both these things have survived over 30 years in storage, and the last thing I want to do is screw them up by being an idiot and connecting them wrong and frying them.

Thanks for any help in advance...
