Audio Adapter Cables for iPod/MP3/CD to Zenith Trans-Oceanic

International customers please read International Customers before ordering. International orders placed without prior approval will be refused and refunded.


Connect your iPod, MP3 player or CD player to your Zenith Trans-Oceanic radio without adapters. We hand make these custom audio cables specifically to allow your portable music device to connect to the RCA female mono phono input on select Zenith Trans-Oceanic radios without the need for special adapters. The cables feature a right-angle RCA mono male connector and either a 3.5mm stereo male connector or 3.5mm inline stereo female connector on the other end. The mono signal is derived by summing the left and right channels through two 2.2K resistors embedded in the RCA mono plug body. Constructed with quality shielded audio cable.

The right-angle RCA connector allows the rear lid of your Zenith Trans-Oceanic to be closed while using your iPod, MP3 player, or CD player.

Convenient 18" length allows your cable to remain inside the radio when not in use. Just plug it in and leave it.

Compatible with the following Zenith Trans-Oceanic models which usually have the phono input jack:

  • 600 series tube Trans-Oceanics with phono input (all models except L600, R600, and possibly some early T600's)
  • Royal 1000 solid state Trans-Oceanic with phono input.
    • RCA audio cable to iPod for Vintage Antique Radio Zenith Trans-Oceanic
  • Royal 1000D solid state Trans-Oceanics with phono input.
  • Royal 3000 solid state Trans-Oceanics with FM output


    • The adapter cable may also be used with the Royal 7000, 7000-1, and D7000Y series radios, but some modifications may be necessary as the RCA phono FM output jack is located inside the back cover on the first generation Royal 7000. However, most Royal 7000-1's and all D7000Y's should have an externally mounted 1/8" mono jack jumpered to the internal RCA phono jack (see photos below). Check your radio before ordering to see if it has the externally mounted 1/8" jack.

  • To use the cable with the Royal 7000, remove the three screws at the bottom of the rear cover and loosen the panel enough to insert the cable's RCA phono plug into the FM Out jack. For a more convenient arrangement, install a panel mount RCA phono jack or 1/8" mono jack on the rear cabinet cover as with the 7000-1 and D7000Y.
  • To use the cable with the Royal 7000-1 and D7000Y, purchase the RCA phono jack to 1/8" mono adapter listed below. You would also need the adapter if you modified your 7000 by adding an externally mounted 1/8" jack.











    • To use the adapter cable with solid state Trans-Oceanics with an FM ouput instead of a phono input (3000, 7000, 7000-1, D7000Y), insert adapter cable plug into the FM OUT jack, and turn the band selector knob between bands to kill RF reception. Note that the Royal 3000 FM Out jack is in the same general location as the Phono In jack on the Royal 1000 and 1000D, but there is no switch. The Royal 1000-1 and some 1000D's may not have the phono input. Check before purchasing.

    The adapter cable may also be used with other vintage radios with an RCA phono input. Do not attempt to use this adapter with any vintage radio that does not have a factory installed phono input. Serious shock or injury could occur as well as damage to your device.
