You can use either of those two, the bottom right or the top right. Those two are both 8 ohm jacks. What the 2x16ohm means is that if you had TWO Marshall or VHT cabs that are 16ohm, you would plug BOTH cabs into those two same 8ohm jacks If you had just ONE Marshall or VHT cab rated at 16ohms, you would plug it into the single 1x16ohm jack all the way to the right in the first pic.
When you are using multiple speaker cabs, your total ohm load changes. If you were running TWO 16 ohm cabs, you divide that number by 2. That gives you a total of an 8ohm load. Peter tries to make things simple by the way he labels the jacks, that is why it says 2x16ohm over the two matched 8ohm jacks. Same goes if you had TWO 8 ohm cabs, divide by two equals a 4ohm load. You would use the two jacks all the way over to the left. The reason why there is just a single 16ohm jack is because there are no 32ohm cabs. It is impossible to have a final ohm load of 16ohms with more than one cab.
2007 Diezel VH4 EL34 and 12ax7 Ruby..Working perfectly an amazing sound and I really love it
But wanna try something different.
How many the preamp tubes do I need for channel 3 if i swap to another brand?
JJ ecc803s will work with and need to do bias?
