[drakelist] TR-7 10volt R and T lines

I recently had an issue with my TR7: the 10R and 10T lines appear to both be high ~ 8.5 to 9.5 volts at the same time. I replaced the 2N4402 transistors with 2N2907 (the parts guy said they were equivalent) and get the same results. What do I look for now? Thanks Steve KD2ED

Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Steve - Usually these fail open as a result of the R or T lines being shorted to ground, even momentarily... Any event that led to the problem?
