Hi, Does anyone know about when, by serial number, Drake went to the newer version 2nd IF-Audio board?
As much time has passed, I know that unless one is sure his/her radio is original, it may be hard to tell due to possible board changes before the current owner. But does someone out there has a good idea? FYI, my current TR7 is SN, 5392, split rear panel, late version NB, Late version pre-driver, early version digital control board and early version IF/Audio. I may be wrong, but the NB is likely a newer addition. I did notice that my IF/audio board has been repaired, an IC replaced and a poor soldering job that I had to clean up. I guess, bottom line, I'm trying to figure out if my audio board is original to the radio or not. Thanks, David WD9CMD
