Anybody use a switch after the speaker taps?
I have a pair of HE-5LE's on the way; not HE-6's but a similarly difficult drive. Lower impedance tho, 38 ohms. I plan to run these off of the 16 ohm speaker taps on a DIY tube amp, push-pull 2A3 that puts out about 12W into 8 ohms (actually 6B4G, 6.3v filament octal base version of the 2A3).
I might get by without a parallel resistor (reflected impedance the tubes would see might be inside "normal" curves), but I'll start out with a 30 ohm. Should give me 16 ohms load on the output transformer. A little more than half of the power will be dissipated by the resistor so I should get roughly 5-6W (8 ohm equivalent) power on the phones - just about right I would think.
My issue is switching between the headphones and the speakers. I need a switch. As much as I loath junk in the signal path, swapping cables every time between speakers and phones isn't a viable option. Speakers are on the 8 ohm tap, not sure it that will make the solution easier or more of a mess, haven't thought that through...
Any ideas? DIY is no problem.
Adcom has a couple that would work. They are on sale at the moment. http://www.adcom-usa.com/speaker-selectors
