This is a beautiful condition JB 12 modulator. The unit has been updated with a brand new power supply new 6BQ5 tube and a more stable relay and keying circuit installed as seen in the photos. This is a LOW DRIVE UNIT ONLY.. 2 watt dead key with 10 watts on swing produces maximum output at 60wts any more than 10 watts could blow this unit to the Moon. So please only offer on this unit if you know what it is and how to respect it. Due to parts scammers thieves and dishonest idiots this unit is being sold as is with absolutely no returns accepted whatsoever. Use the photos as the main description because what-you-see-is-what-you-get and nothing more nothing less. No International offerding accepted and the winning buyer pays $20 shipping. Thanks for looking and happy offerding
