Can't remember how this works. Would this be okay?? Not a very powerful 16 ohm amp.
Nope.Lowering the speaker impedance stresses the output transformer, causing overheating and possible failure of the transformer. Big iron transformers, like those in old Fenders and Peaveys, can normally handle it for awhile. That doesn't mean it's a good idea.
Going the other way, 8ohm amp into 16ohm speaker, doesn't do much damage, but you lose a lot of the amp's efficiency.
I'm not experienced with those amps in particular, but you should have no issues. If it was an old Fender you wouldn't ever worry about it at all.The amp is a One watt Marshal DSL tube amp. I also have a 15 watt Fender with an attentuator. I have a 1x10 cab with an 8 ohm speaker I was hoping I could just flip the chord from one amp to the other. I just play at home in an apartment. Don't want to get another cab. Stacking one head on top of the other fits nicely, especially in an apartment
Only read the last line? If you are going to mismatch it is better for the transformer when output in ohms is larger than the speaker. If the transformer has less ohms than the speaker you take the chance of overheating the transformer.A speaker with a bigger number of ohms plugged into a transformer with a smaller number of ohms?
They do make a 50W version and you can buy the transformer.
I bought my 50w one on here for 100 used. My 45W Super doesn't seem to stress it any.They do make a 50W version and you can buy the transformer.
Peavey used to sell one that could handle 400W that was a repurposed 70/100v line transformer. There are 2W and 5W line transformers, I couldn’t find one that was really cheap from Hammond, but I’m sure there are cheap ones out there.
I was reading some information about using a line transformer for impedance matching. I went in pretty sure I understood everything and came out needing a break. I stopped part way into Turner of Australia’s explanation.
Number one. That being said, a 100% mismatch up or down should be easily tolerated.This is getting more confusing. Experts here,... if have only two choices, which is potentially less a hazard, less stress on the transformer ,...
1) 16 Ohm amp into 8 ohm speaker,... or 2) 8 ohm amp into a 16 ohm speaker
Agreed. I look at this way, NEVER run a tube amp without a load attached. They don't like high impedance loads. But, you can actually short the transformer and you will do no damage. In fact, Traynor used to use shorting jacks on their heads, so if the speaker got unplugged, there would be no damage to the output transformer.Number one. That being said, a 100% mismatch up or down should be easily tolerated.
