The price is for one tube, either NOS or very close to NOS. This is a small double triode tube featuring gray plating and one D-shaped getter. It has a noval (B9A) pin base and was produced in the Eindhoven plant, Holland in the late 1950s. This is the first ever PCC88 type, marked with a pink etched code between the pins on the bottom: DJ0 6?7C.
It has been tested VERY STRONG with the following results:
Testing was conducted under the following conditions: Uf = 12.6V | Ua = 250V | Ug1 = -2.0V. Good starts at Ia=8.5mA and 100% is Ia=15.0mA.
This tube is EXTREMELY RARE! There are VERY FEW LEFT from those!
