one Metal Ceramic Planar Triode , NSN 5960-12-165-6996
High Power, High Precision Special Purpose TYPE  for Professional and MIL SPECS - Application i.e. in AIRBORNE  PULSE RADAR DEVICES

Manuf.  THOMSON TUBES / THALES / EADS

Model: YD 1048

manufactured 07/2003 by THOMSON TUBES ELECTRONIQUES ( FRANCE ) ; NEW and originally packed - see PHOTO

the here offered tube has much higher specs and reliability than the normal on the market available YD1048s from SIEMENS or others, which are out of old stocks and have been manufactured in the 1970s

the tubes are all packed in sealed TULBS with moisture protection and will be delivered in this TULB
we have > 50 units available.....see PHOTO .... please ask for special offer for larger quantities

as you can see on the PHOTO of the Purchase document, the tubes were bought for a price of > 900 Euros / per unit
