Anyone know if tungsols are still bad for cathode and PI?

I have a few that I bought about 6 months ago and am using them in all four slots after one of the stock ARS/JJs went microphonic on the BE and currently they sound great, but I just remembered they had issues with voltage in cathode and PI placement. Is that still an issue or has new sensor resolved their spec problems?
Also, anyone know the tube layout for the pink taco?

Thanks
 
i too am curious about this for my JJ... i used to have a Rivera K Tre that i was running all tung sols in, but was warned about the CF trouble that tung sols have. i never had a problem with them in the Rivera, used them for about 6 months and then switched to all chinese before eventually trading that amp...
 
Alright I'll stick with the chinese in v3 and v4 then. Would I be correct in assuming that on the PT20 v1/v2/v3 is Preamp/Cathode/Phase inverter? So chinese in v2 and v3?
