Help! can't find ef86 on my Hickok 539b roll chart! and need a tube project

famousmockingbird · 18th February 2011, 12:11 AM

I have a couple Telefunkens I would like to test but can't find it on my roll chart, I also tried looking for 6267 and nothing

If anyone has the switch settings I would greatly appreciate it.

Also I would like to start a project with spare tubes. I don't want to spend a lot if scratch on transformers, so maybe a headphone amp or a phono preamp ( MM ).

Tubes I have: 12AX7, 12AU7, 12AT7, 6SN7, 6SL7, etc...

Try 6267, that's the same tube.

Thanks bob for the quick reply. Trying to find the 6267 was my second course of action before bothering the kind folks on here. I actually think you were the one who gave the 5Y3 switch settings to me so thanks again.
