Rogue Zuess tubes won't bias in Ultralinear mode

Thanks, The line voltage appears fine but I'll investigate these other possibilities after the holidays. I don't want to put the amp down at this time of year. I appreciate your thoughts. Thanks.

I had an issue with a rogue 99 per that they could not reproduce sent to them twice and in the end they believed me and replaced some parts they thought would be causing the problem (despite their not seeing it) and it has been fine since ( more than 2 years). I suggest you work with Rogue they are great.

Thank you, the problem with shipping the Zuess back and forth is that it weighs over 200lbs without the packing and pallet. It cost me over $400.00 in freight alone to send it last time then their upgrade charges were on top of that. I agree that they have an awesome crew up there and they really tried to figure it out but couldn't duplicate it. They are a very nice bunch indeed. Next time I'm going with the mono blocks. I'm looking for ideas so I can try to have it looked at locally. I appreciate your response.

Next time I'm going with the mono blocks.

Exactly my feelings after selling a Krell FPB600 ... in the future, only mono < 150 lbs so I don't need freight service.
