I have a small 8W homebrew amp that has an 8 ohm output. My problem is that I have 2 8 ohm Vintage 30's (I know the amp barely drives the 60w speakers, but it sounds good). I would like to drive them both and have concocted a few solutions and I wonder which is best for the amp, so here goes:
1) I have a 16 ohm and could wire the 2x8 ohms in series (16 ohm) then in parallel with with the single 16 ohm to get myself 8 ohm. Problem is I don't really want another speaker in the mix, but it would work, right?
2) Might I use an 16 ohm / 15W or 25W power capacitor in place of the 16 ohm speaker in the last setup as a dummy load? Something like this:

3)Last resort is to go into the amp (it has an OT with multiple taps, 4,8,16) and convert to 16 ohm or install 2 separate jacks, 8 and 16 ohm or add a switchable output load. I'm confident to do the first, the second I have a few questions but could do, the third I'm not so confident.
4)My last question is if I go with a 16 ohm dummy load should I be using something like this:

is it important in this application to have that dummy load react like the speakers it is running in parallel with?
I know I've asked a lot of questions and Thank you to any who would take time to solve even one small piece of this puzzle.
