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.

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
