There is a 5TP4 listed on 'bay under Item Id: 160527106121.
It is untested.
Is there anyone among us who is available to test it for those of us who are still interested in these old things?

Thanks and Happy New Year,

It has some Phosphor burn so it's definitely used, that doesn't mean it's not good though.

I have a TP400 tube in a Philco that the phosphors are really dark and it's still plenty bright.

Thanks Eric.
I had noticed the telltale permanent 3"X4" rectangle in the center of the screen.
I have been looking for a good used 5TP4 for my projector test setup. This may be a good candidate, if it checks o.k.
