Hello!

I recently acquired one half of a Traynor-Norelco YN-412 4x12 Speaker cabinet that had been cut in half and made into 2 separate 2x12 cabs. It has 2 Phillips Norelco "twin cone" whizzer speakers in great condition. I also have a Sovtek MiG-60 amp head, which I have been looking to get a better cab to play it through for a long time. I know the cab works, because when I used it to run my PA mix through at a rehearsal, it sounded GREAT. The problem arrives when I plug my Sovtek into the cab. It sounds like the signal is being overloaded, and distorts - no matter how high or low the volume is. I just got my Sovtek Head serviced last week, so I know that it is in great condition and doesnt have any other problems with other cabs. I am wondering if it may be the wiring configuration in the cabinet itself. I took photos of the inside of the cab and put together a diagram of how it is wired. Can anyone help me? My band is playing with Jonny Lang on Friday and I'd love to play with this cab!

Thanks!

I could be wrong, others may know for sure, but I think you have a classic parallel wiring configuration there, which lowers the overall resistance, or load impedance drops, and your amp may be overpowering them. If they were done in series, it might be the right impedance for your amp's output; since it is a Marshall knock off, in the 8 - 16 ohm range, and not 4 which you could have? I'm not sure about that, but your individual speakers are rated at 8 ohms apiece, and 4 might have originally been 2 ohms? I don't know how low your amp can go?

Also, even though you have had your amp serviced, the tubes may not be able to handle the plate voltage that your point-to-point 60 is running, at a 650 plate voltage as compared to around 500 in the Marshall.

So, look to see if your amp has tubes that are capable of running hotter such as the 6550's or KT88's instead of EL34's.
