NOS teslas (12ax7) are currently in mine. I have used Electro-Harmonix and the Sovtek LPS as well as the stock tubes. The LPS may be one for you to try. They're only about $12 each. Though not as quiet as a NOS they do sound pretty good.
What tubes for a EAR p834
I have a EAR P834 with hovland cap upgrade. It has the stock tube (JAN 12ax7, I think). I have heard the the Telefunkens sound amazing in the Ear, but the cost for retubing would be more than I want to spend. Does anyone have any sugestions on curently produced tubes that could get me great sound? Or should I just save until I am ready to get the Teles? Thanks!
