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?

TEK no longer knows what the specs are,their IC/hybrid manufacturing unit was sold to Maxim long ago,who then forced a last-time buy and ceased production of TEK-made ICs(155 and 234 prefix ICs).That's what terminated the 2400 product line.I doubt you could get Maxim to release the specs. TEK will have nothing to do with these scopes.
This H-output amp is a differential output amp with high linearity and very high freq response(to display a

There have been several threads on this problem and there appears to be no repair.
