Default Re: Tektronix 465B Scope - Some problems.

Make a note of which cables go where, and with the scope switched off, disconnect all the coax cables toward the rear of the Y amp board (they are the ones with the little gold plugs and sockets on them) Make sure the ends don't short out on anything.
Then switch on, and you should have the timebase running, but no signal influence from the Y amps. See if its any better.
