Hey Everyone,
I have finished a Tram D62 repair and alignment by using the Cobra 132XLR info as I cannot find anything specific to the Tram. I was able to find a few differences but there was one VR that I cannot seem to figure out what its for.
Now there's a mystery. The Sams shows a medium-fat electrolytic cap in that spot. A transistor next to it is TR24, but all it does is switch 8 Volts to transmit.
Must be a later revision of the circuit board than the Cobra.
Sams CB179's grainy monochrome pics do not show a circuit board number where the above pic shows KNTB001 at the upper-right hand side. Sounds like two different revisions to me.
This radio uses a double-sided circuit board with foil traces running between the components' legs on the top side. This makes manual tracking of the foil traces a lot tougher. A single-sided pc board is a lot easier to trace out.
