Tungsol invented and introduced the 5881 and 6550. The Tungsol 5881 had a miconol base, sort of a tan brownish color. Transductance of each of these types was superior to anything made by competitors. Both types are beam power tubes. I am curious how the 5881s are being used in the Supratek circuit.
Tungsol 5881's
I've got a Supratek pre with 5881's and haven't gotten around to rolling out the Sovteks (arrghhh!! groans from the gallery...).
Yes, Tungsols, and yes brown bottom, but what iteration?
I see references to double D getters, short bottles, some that appear to be JANs etc.
What do I need to get/ stay away from?
Please, educate me!!
Thanks,
Mark
