Found a tube in old tape recorder (pics inside)

[c.t.d-nicke]

Just want some information about this tube and if it is useful in my roadster.

Found it in an old tape recorder.
It's a Valvo ECC83 with 165 (mayby I65, cant see if it is 1 or I) and 49L2 etched on it.

Any help is welcome

Good or bad sounding in a dual rectifier and in which position?

Thank you

Looks like a Philips Short Plate (15mm) ECC83 from the mid 60s.....rare find and definitely a nice sounding tube.
I´d just try it in each position....

+1. With an etch code of I65 delta 9L2, it's definitely made in the Herleen, Holland plant. Among Herleen-made tubes, these are the "Most common type - good standard quality."

These are among my favorite tubes. I find them bright and articulate but not harsh, and balanced across the mids and lows. I have at least one in both my Mark amps.

That is one sweet tube you have, yep, Amperex short plate, Heerlen plant. Schweeeeet!

great find!

great sounding tube, likewise, one of my faves, as i have 5 or 6 of them laying around.

great in any position, and a GREAT sounding reverb tube despite what some people might think.

Love that tube. I have several Amperex Harleen I65's, mostly the Hammond versions. They really do add something special wherever I put them. Congrats on a nice find.
