(5) 27 ST Radio Vacuum Tubes
- Source: eBay
For your consideration I have (5) vintage 27 ST vacuum tubes, 4 are National Union 1 is Kenrad.The Kenrad tested 1300/1000, the other four National Unions tested 1500/1000(2), one tested 1600/1000, and the final tube tested 1650/1000. Tested them all using my Hickok 600 tube tester where 1000 on the meter was a good tube. I pack the tubes using plain white tube boxes, wrapping them in bubble wrap and using styrofoam peanuts to surround them in the packing box, they travel well this way. Any questions please feel free to email me, thanks.
