5894, 6907 & 6252 Transmitting Tubes, 11 Total, (see description for details.)

Description

5894, 6907 and 6252 Transmitting Tubes, as Follows:
1)  5894:  (6 total.)   Twin beam power tube.  5894B/8737:  The single one (photo) near its box is a new tube that was marked "OK", and appears to have never been used.  Getter is perfect.  The other one is used, and appears in the picture of 5 tubes.  The getter on that one is "fair".  5894A:  One of these, used, getter is "poor".  5894:  3 of these, getter is "fair" on two, it is "good" on one.  All are Amperex.
2)  6907:  3 of these,  used, all G.E.  One made in USA, getter is "good",  the other two made in Holland,  one with getter "fair", the other with getter "good"  (These appear to be similar to type 6252.)
3)  6252/DX142,  two,  used,  both Amperex.  Dual tetrode tube.  Both getters are "fair" to "good".
I applied voltage to filaments of all 11 tubes and all glowed very nicely from 6.3 VAC from my vintage Lambda power supply.  Other testing and evaluations were not possible, such as emission, so these tubes are being sold "as-is", with their level of performance in a transmitting circuit unknown.
