Q: What should I consider when selecting a speaker cabinet for my SNK Amplifier?
A:The important thing to keep in mind when selecting a cabinet for any of the amplifiers is produce is the wattage of the amp at the given impedance of the cabinet.
A 4ohm cabinet needs to handle a minimum of 300w. 8 ohm - 150w and 16 ohm - 75w
A single speaker cabinet would be a very limited option but there are some high wattage neodymium 12" speakers available on the market that would work.
A 212 or 412 cabinet is probably a better option though. An 8ohm 212 or 412 cabinet with 150w handling should be an easy thing to find. This would provide you the option to connect a second 212 or 412 cabinet in parallel to bring the total impedance to 4ohm and utilize the full 300w output of the amp.
Another option would be to get a 412 with 300w handling that has a 4ohm/16ohm switch to have access to 2 different amplifier wattage depending on the situation in which you're playing.
Q:Can I run my amp without a speaker connected?
A: Yes, you can definitely run any one of the SNK amps without a speaker load due to how the class D power amp
Q: My amp is cutting out.
A: If you ever run into an issue with your amp, start by reducing your setup to the it's simplest form. Instrument into amp into a single cabinet. If you still have issue, check cables.
Now with that said, it is important to keep in mind that the class D power amp in all SNK amplifiers is sensitive to the impedance to which it is connected. The absolute lowest speaker load that the amp can work on is 2.66 ohms which is achieved by putting a 4 ohm and 8 ohm cabinet in parallel. If two 4 ohm cabinets are connected in parallel, the total load will reduce to 2 ohms and the amp will go into protection mode when signal is passed through the amp. Sound may briefly be heard but it will only last a short amount of time. The amp will reset itself when the signal is stopped.
Changes in impedance while playing can also cause the amp to go into protection mode and "cut out". This can occur if there are any loose connections at the speakers itself. Frequently, speaker cabinets are assembled with push on connections that can become loose over time. Your tube amp does not have a way to react to this change in impedance and will continue to play as one speaker in a multiple speaker cabinet cuts out. That's why a cabinet may work without a perceived issue with a cabinet while a class D amp may go into protection. It's recommended to check all speaker connections if a cutting out situation occurs with a particular speaker cabinet.
Q: My amp or pedal needs to be fixed, can you do that?
A:You bet I can! And if you're the original owner, it will most likely be covered under warranty. You will be required to pay shipping each way though, assuming the issue didn't occur upon receiving the unit new. In that case, you ship it to me and I'll cover return shipping.
If you aren't the original owner, you will be responsible for the shipping and any fees for the repair to be assessed on a case to case basis.
