Siemens DG7-32 Marantz 10B Tuner CRT ELECTRON TUBE NEW IN original Packaging! Condition: NEW OLD STOCK. Shipped with USPS Priority Mail. Only opened one to show condition. I own two 10B tuners and wanted spare tubes for them. So years ago, I found and bought a case of these. Recently, I stumbled upon the box in the basement and realized that I don't need more than two spares, so I'm selling a few. Oscilloscope tube, scope tube NEW EXTREMELY RARE!!!!
