Default Re: Tektronix 465B Scope - Some problems.

Dave, we need to find out the source of the interference, personally I would remove the y pre-amp and input selector pcb, so that you are left with just the timebase, which will still operate. This also gives you the opportunity to properly clean the switches. I can photocopy the 465 manual y pre-amp removal procedure and send it to you, if you pm me your email address. Obviously there will be some differences, but if you hit any snags, you can work round it. If the interference disappears, you will know where to concentrate your efforts.
