It has identical specs as RCA 6SN7. Many of our customers including tube amp manufacturers have used it in place of other 6SN7 and no one ever reported a problem. Hope this helps. If you have further questions please feel free to ask us directly if you wish. Best, Rachel @ Grant Fidelity

Beyond which there is plethora of superb 6SN7s to roll. The Black treasure should cause no harm I would try it. Don't hold me to to it perhaps another roll would be better.
