Re: Tektronix 475: No Horiz Sweep
Mr. B
Thank you. I did eventually realised that a summing transistor would not reveal much with voltage measurements. I also, as you suggest, already tried disconnecting all other inputs, Q1332 and the other 2 coaxs - made no difference. Nor does lifting CR1337.
Of course I am only able to look at one side of the board without removal, maybe there are horrors on the other side?
I wonder about breadbording Q1338 and 1344 - seems a bit desperate!
