VTL 2.5 without stereo output

All of a sudden my preamp is providing mono output only. There is no mono switch or any other internal switches. I swapped the tubes (left to right) which didn't do anything. It sounds fine excep for the lack of stereo. Any ideas as to the possible cause? TIA

Maybe a dumb question on my part.

That VTL preamp has two pair of RCA outputs. Any chance you were swapping interconnects and accidentally plugged into both left channel or both right channel jacks?

Hi Albert,

I had the same thought. All connections are correct.

You have a puzzling situation, perhaps call VTL and ask for help. I'm not coming up with anything else.

Hopefully an Audiogon member with your same preamp will chime in.
