I keep seeing messages about the Tek 24xx faulty horizontal output
chips. Now, I don't actually HAVE a 2445 or 2465 (much less, one
suffering from a faulty U800 chip) but I'm very curious. The
descriptions of the chip and the effects of its failure suggest that
U800 is some kind of high frequency amplifier. Wouldn't it be possible
to rig a replacement for the chip from discrete components? What are
the specifications for the chip?
