Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

update

I found a program that calculates impedance for speakers in parallel (see link). According to it if I put a 10 ohm resistor on each pair of speaker terminals on each amp, when an amp is connected to the speakers the impedance will be 4.4 ohms. These are 30 watt skookum resistors so they should handle the load on idle. This would seem to be the easiest and least expensive solution to do some A/B comparisons. I know the resulting impedance isn't a perfect match, but it ought to work for an A/B test I hope. Does anyone see major flaws with this?
