YC-156/ YC-179/ 3CPX5000A7 Tube. This is a YC-156 tube which has the exact same structure as the YC-179 and 3cpx5000a7. It was a pull from a transmitter. The multimeter clearly shows the filament is in tact and that the other tests show its not shorted. This is sold as is and for parts not working. This sale is for one tube only. Nothing else that is pictured is included. The multimeter and other tubes are not part of the sale. Shipping in the Continental U.S ONLY. No returns and by bidding you agree to the above stated. There are Lethal Voltages related to these tubes. No liability lays on me on how you use this tube. No liability lies with me in any harm that could occur from any mishap. Thanks
