Urgent OHM question

Urgent OHM question
Hey guys, quick question. There is an amp head for sale locally I want try out. It has 2 4 ohm outs. I only have an 8 ohm cab. WOuld it be ok to plug in the 8 ohm cab just to run a quick test on it?

I am planning on heading out soon, so any quick reply is appreciated lol.

Thanks

What amp is it?

It's an old Garnet "Tripper". Technically a vocal PA. 6v6. Can be used for guitar.

Sure it'll be alright to test it. Sounds like a cool amp!

Ya, hopefully I can get it!

I just plan on giving it a few minutes to make sure it's functional.

Most amps/speakers will handle a 2:1 mismatch, at least temporarily. Make sure it's set at 4ohms and I wouldn't necessarily use the cabinet long term if you buy it.

While I have people's attention. It's not a topic I know a lot about. Any heads I have owned have had different inputs for different ohms.

There is 2 4 ohm outs on the this head. What are my options as far as speaker combinations? If I ran one of those outs to a 2x12 cab, would would the ohms of the 2 speakers need to be?

The head is a good deal, but I am just trying to figure out if it could be too much hassle/cost to get a speaker solution worked out. I only have a 1x12 cab with an 8 ohm speaker and one other 8 ohm speaker lying around that could go in an another cab.

2 8ohm speakers in parallel = 4 ohms.

You'll want to consult diagrams. Many available on net. But explaining series, parallel, series-parallel, etc... is kind of a lot for this thread.

pic = 1000 words.

cheers.

Thanks!

It is most likely that the 2x4ohm outlets are paralleled.

In other words the amp expects to see a total load of 4ohm even when two speakers are connected - that is two 8ohm speakers - one in each hole. The total load should always be 4ohm. (that said, a short test at low power with a mismatch 8ohm load won't kill it)

If you only have one speaker then it wants to be 4ohm impedance.
