Default WS-19 sets

If You are going to have a fully operational WS-19 set as a base station or operate it in a restored vehicle it is highly recommended that you take a ham course mainly for legal reasons, fortunately you no longer have to do CW, MCW (that's Morse code) to pass the test.
The radio transmitters can be temperately or permanently disabled if you just need it for the intercom function, highly recommended in a noisy vehicle.
Word of warning DO NOT apply power to an untested radio / power supply that has been sitting in storage for a long time. The capacitors are the paper type and will dry out over time, applying power will result in a direct short.
This problem can be fixed by slowly applying power over a set time period to renew the electrolyte in the capacitors, or replace the caps with a modern equivalent.
Failure to do this procedure can cause all the smoke to leak out of the caps all at once sometimes referred to as the Big Bang. The large cap in the power supply is similar to a small grenade[ BOOM, shrapnel, concussion, shock] etc. etc.
