klm 367 repair

2014-02-23 by <vaporlock_32578@yahoo.com>

Hi to all I have a p6 that is not working I have fixed the batt. problems found a bad ic32 and replaced, and also checked all my traces, but the ic 22 chip gets hot in about 30 seconds I have ohm checked all the pins and all are above 1000 ohms except for the grounds and power supplies. I also have checked with an o-scope and find no signal all pins are between 3.5 and 5 volts, except for the grounds. I was wondering if I can pull ic 22 and test for voltage on the signal lines and such, and if I should see anything on those lines with ic 22 removed? thanks for any help

Hi all,

I need to replace a few ICs on my KLM 367.

I traced out all and fixed the bad connectors and cleaned up a bit but what chips go into IC slots labed IC 30, IC 31, and IC25? ICs 31 & 30 are 74LS08 type quad AND gates but what is IC 25?

Thanks,

Nate

IC 25 is a 4011 Quad NAND Gate.
