A solid working knowledge of vintage electronics is essential in using these service tips. If you do not feel comfortable troubleshooting your own set, I strongly suggest you invest in several good books on the subject of servicing antique radios and study these as you practice on an unwanted radio, until you feel comfortable working on them. Old radios contain high voltages that can injure and/or kill!
