Re: Amp problems? Ohm questions? Amp blowing up for no reason, READ ME!


Hello, American Viking, First I want to thank you very much for this info, I really needed it.

Would you (and any others that don't mind helping), please clarify some things for me?

I have a Marshall cab that has 8 10" speakers [the speakers have the following stamped on them: 10BPGA8C 67 7429] I'm almost positive it is 16 Ohm's. It only has one input and here are the amp heads I have (all Marshall's):

JCM 900 SL-X 100 Watts

MK II Super Lead 100 Watts (looks like a Plexi)

Artist 3203 Valve State 30 Watts (appears to only have a 4 or 8 Ohm selector) Has this Ex on the back 4 = 1X4 or 2 by 8 -- 8= 1X8 or 2 by 16


Are you guys saying that I should set the selector for 16 Ohm's (on the JCM or the MK II) and only run ONE cable from the amps output to this cab? I was told years ago that you could not run a tube amp without BOTH outputs going to the cab and if necessary you should use a "Y" cord if the cab just has one input???

It appears I could NOT run the 3202 with with the 8 10" cab because it doesn't have a 16 Ohm selector.

Have I understood correctly so far?

Part of the reason I ask, is because I'm getting a Marshall VNTG MOD 42B 4X12 SPKR CAB STR delivered tomorrow and I don't want to screw everything up!!

I truly thank you for all this great info.
