Great Question. I have wondered the same thing. My search has led me to the Rogue Tempest which can be switched to triode or ultalinear and the Conrad Johnson CAV 50 which generally comes wired ultralinear but can be sent to the factory and converted to triode. These two units sell used under your cieling. Rogue has auto bias and the CJ is manual with LED's. I'm somewhat new to this hobby so I would also like to hear what the rest of the community has to say.
