Hi everyone, brand new to the forum and I have a question. I am looking for a schematic for a Global Specialties Instruments 20 MHz Sweep/Function Generator. It has no model number on the case, and the main circuit board is marked FG1202-1. The 50 ohm output on the front panel does not work any more but the TTL and CMOS outputs are working fine. All other functions seem to be ok, but I would like to get it repaired and back in service. Any help would be appreciated.
