Help, please: 8 into 16 or 16 into 8???

Thanks, that sound doable even by my standards.

I knew they'd come in handy one day! Okay, so yellow is 1 and orange is 4 and green is 7 and... :io:

You would be best to use a ceramic bodied, wire wound resistor. They look like this

Best to go higher wattage than you need as it will run cooler. 5 or even 10 watt. They cost bugger all. Cheers
Edit: Used in this manner, the resistor will be dissipating roughly half the amps output power as heat. This is why it's a good idea to use a higher wattage wire wound resistor. When playing for long periods a lower wattage resistor will got hot. Cheers

I'm teaching a robotics course at the moment (God only knows how that came about???), and I've decided to add some practical to the theory thus all the students are gonna design, build, write the s/w, etc for a little Arduino robot - I have loads and loads of circuit bits in preparation; resistors, diodes, capacitors, leds, sensors, you want it, I got it. Sadly, I have no idea what any of it does, but I suspect the students will work it out... :p

I have another silly idea...

I love my new little amp and its 8" speaker sounds surprisingly ok, but the separate 1x12" cab sound is too roomy for me in my small apartment (I'd prefer it a bit tighter too), I liked the 1x10s I previously had more than this 1x12. So, there's the possibility that I can swap my 1x12 cab for my old DSL5 combo. But, there's a problem: I don't like the speaker in the DSL5, so I'd throw a 10" greenback in there which I did before and sounds great. But, here comes the 8 into 16 or 16 into 8! In an ideal world, it'd be nice to sometimes plug the Cornell into the 10" Greenback of the DSL, just to get a different sound, buuuut the Marshall is 16 Ohm while the Cornell is 8 Ohm. Buuuuuut, if I was to change the speaker anyways, I could put an 8 Ohm or a 16 Ohm in the Marshall, so we come back to:

1) Would the Marshall 16 Ohm amp be better with an 8 Ohm speaker that I could also plug the Cornell into. I don't mind losing some volume with the Marshall, but I don't wanna blow a transformer. I don't mind reducing life of tubes, but I don't wanna blow anything up or damage circuitry.

Or

2) Would a 16 Ohm Marshall amp and speaker be ok to plug the 8 Ohm Cornell amp into (this is the idea that worries me; I don't wanna take any risk at all of damaging the Cornell amp...).

Or

3) Are they both stupid ideas.

I'd like to have the Marshall sound and the Cornell (AC-ish) sound too. Marshall on the floor, Cornell sitting atop - happy days. :dood:

How many watts is this amp?
 
Yep 5, but I usually use it on the lower power settings such as 1/8th Ohm. Thus, I'm thinking that time to time, using the 16 Ohm speaker should be fine although I'll probably have to use the 1/4 Ohm or 1 Ohm setting to balance the perceived volume out, but that's fine as I get a bit more headroom.
