This EF Johnson Viking 500 AM/CW Transmitter & Power Supply, are both in Excellent Cosmetic Condition and have been fully restored by Jim Millsap W9CTO.
Jim is well known and is one of the best Radio Technicians still restoring Vintage Radio gear.
This unit has had all the electrolytic capacitors replaced. There is a complete Cable interface set which has been made with modern High Voltage Wire and is much safer than the original cable set. In addition to that the AC cord is new and this unit is wired for 230 Volts AC.
The Terminal Strip cover for the RF deck is included and was not installed when I took the pictures.
For the most part everything is original with the exception of the HV rectifiers. The original 866 Rectifiers have been replaced with a modern Diode Board which provides much better regulation and is less likely to arc and cause the common problems of mercury vapor rectifier tubes.
The Clipper circuit has also been disabled to prevent maladjustment and distortion. The complete circuit is still intact and can be hooked back up with the attachment of one wire.
The paint on both the RF Deck and Power Supply/Modulator deck is very nice and has some light marks but looks great. Even the long and short screws are all original. The Chassis on both pieces are very nice with some spots but no bad rust or corrosion.
The RF deck face and cabinet have only a few small marks from normal use. The cabinet on the power supply is also very nice.
I also have the original key needed to operate this transmitter.
The Terminal Strip covers are not included. It is just a bent metal cover and one can be made and should be added for safe operation.
I will also include a nice copy of the manual.
It is very rare to find this transmitter and even more rare to find one in this beautiful condition fully restored.
Please contact me for payment information BEFORE you purchase this transmitter. (No Paypal or CC)
This is a pickup item only. If shipping arrangements must be made, it will be at the risk of the buyer. I am one of the best in the business shipping heavy vintage gear but the power supply modulator is very heavy and difficult to ship.
I may be able to arrange delivery at the Orlando or Dayton Hamfests, or within a reasonable distance from where I live which is northeast Wisconsin.
