I dont understand the switching on my TL - SSE. It uses Hammond 1628sea connected to speakers at 8 ohm taps. When I change the Switching positions for UL or CFB I don't hear any significant change in volume or sound quality. I have used DPDT on -off-on switches as suggested in the guides. Is there any risk of damaging the amplifier if it is powered up and used with switch in the wrong pisition. Eg the off / centre position. I only ever run mine with these switches in one of the on positions (up or down position) because I am worried about damaging the OT's or something. As I said though I hear no difference and am wondering if this ia becauae i should be switching between on and off.
I just finished wiring the UL /Triode switch and found a big difference. In Triode the valves had a 'in your face MIDRANGE' that was impossible to ignore. With UL, that settled down nicely.
My speakers are Altecs, what are you running? Maybe that makes a difference too.

Frugal horns with MA alpair 7.3 drivers. What switch did u use? Was it on -off- on? If so what position is the Ul engaged please. Thanks. The OT are massive 5kg each. I wonder if this is why.
I built a SSE many years ago. Still very reliably in use. Uses Transcendar 5K:8 OPT. Usually run EL34 or GLGGC. Sounds great! I found a small difference in UL vs Triode. I like both. Both good depending on volume level and type of music. The CFB I never use..it drastically lowers the volume while at the same time seems to put a veil over the musical peaks resulting in lifeless sound, as if someone just threw a heavy blanket over the speakers.
