[QUOTE="bema, post: 948720, member: 366229"] It's not that difficult to do some reverse engineering. Most of the components have some label/marking. If you know (or can guess) what is does, you reduce the number of vendors. I have done it for BU Quattro (The RF path components). E.g. low noise GaAs transistors are in most cases Renesas (former NEC) or e.g. Mitsubishi. In some cases Avago is also used. The circuits with red marks are bias circuits for the FETs. If you remove the cover like this the DRO might get out of frequency. There is probaly one screw directly above the DRO and this is tuned after all the screws for the cover are tighted. There can be some minor change now when put the cover back again. The switching is not difficult to find. Just follow the line from the F connector. It's done at IF. [/QUOTE]
