Original box?

This is just a note in case the buyer doesn't understand fully what a 7308 tube is.  It is NOT a direct replacement for the 6DJ8/6922 tube.  The 7308 is 7 volts, whereas the 6DJ8/6922 are 6 volts.  Most circuits can handle this difference, but make sure yours does before buying.

PM sent for the 7308.

I guess it depends on the tube's maker.  The "7" out front is supposed to indicate 7 volts, like th 7308 and the 7DJ8.  Some manufacturers probably didn't follow that protocol and rolled out some "7" tubes at 6 volts.

The PCC88/7dj8, which I also own and listen to, is not the same as the 7308. The "7" does not always indicate the heater voltage in every circumstance, and certainly not here.

Most books and data sheets don't even have figures for the 7308, instead only "see 6dj8/ECC88."

 

At any rate, the tube has been sold.
