possible problem with my sse
I have maybe 5 or 6 hours on my sse and tonight i noticed a little distortion. Sort of a fuzzy breakup on loud notes and worse at full volume. I don't think i heard this before. Any thoughts on this? Thanks in advance.

Do you get it in both channels? Triode or UL? CFB? Tube or SS rectifier? Maybe you are just hitting clipping and you hadn't noticed it before? How sensitive are your speakers and what tubes are you using?

It was in both channels. Triode mode. Using tube rectifier, kt-88's. Sensitivity 93. R17 and R27 are 470 ohm.

Seems like a decent combo. What OPTs do you have? I'm just thinking that you have only used it for a short time and that you might just be driving the amp into clipping and didn't really notice it before. You've only got 5-6 watts to work with in triode and the amp has more gain than some. Mine will clip at about "85% line-level" volume (no preamp). How loud are you playing it?

Might want to check your B+ to see if anything has gone awry in the power supply.

Update. Thanks for the responses. I switched cd players and it seems to be fine now after some listening. I had been running a yamaha dvd/cd player changer. I noticed that the mode selector (stereo, dolby, surround) was acting up a bit. I am keeping my fingers crossed here, but it looks like that may have been the problem.
