Reader William Charanza contacted us with a spare wheel issue. Eric cc’ed me to help with a response.
Answer given, a while later, William contacted us with a “knotty Radio question”.
Here’s what William had discovered as he contemplated the servicing of one of his Sapphire V Radios. He has Sapphire V Radios with two outer case configurations. His question:
“Hello Sir, question for you on the Sapphire V. I have 4 of them–2 of one “kind” and 2 of another “kind”–the two sets are different. What can you tell me about the differences? Pictures attached.”
Not having a ready answer, I sent William to Richard Langenwalter, a noted Vintage Volkswagen Radio Specialist in Colorado. I told William to let us know what Richard had to say on the question.
Indeed, very shortly, William shot us the message which he had received from Richard.
“There were three Sapphire V models manufactured for 1967 which are 7BV, 7BVX and 7SMV. The model numbers are stamped into the sides of the radios.
Bendix Corporation made the 7BV and later 7BVX models. These models are distinguished by the power transistor located at the upper left front. The 7BVX model has a small blue transistor.
Motorola manufactured the 7SMV model with the power transistor mounted on the right side.”
I have known for years that both Bendix and Motorola supplied Sapphire Vs for 1967 Volkswagens, but I did not know how to distinguish them. Now, we are armed with even more technical information about our 1967 Beetles!
Questions from Readers often put us on track for such advances in the understanding of our Vehicles. I encourage questions.
Thank you William for posing this question and for following through with your discoveries!
Many thanks, also, to Richard Langenwalter for taking time from his schedule to help further our education about our 1967 Beetles.
I called, subsequently, to speak with Richard. We had a great conversation about things Volkswagen and more!
