All tube operating points below are by no means definitive good sound recipe for your particulate tube project. Lowest THD point is not necessary best sounding one and there is always some variance even in a NOS tube batch from the same manufacturer!  Below information is only useful as a general starting point and is ment to get you in a ballpark when no measurement equipment is available.

Lowest THD operating point spectrum

 2.5mA, -1.19V BIAS, 238Va

Other operating points

2mA, -1.45V BIAS, 237Va
1.4mA, -1.85V BIAS, 240Va

Not particularly linear triode (same as E83CC) but has a clean spectrum. Still usable. Available for sale.
