Re: DC508A Display

 

Ah yes, those Signetics 8T06s. When I saw those I worried that my
SG503 would never be repaired by luckily the problem was in the
preceding 7475 latches.

The same 2 transistor modification should work; except for 10 through
15, they have the same BCD to output decoding.

Hi Ed,

Yes I agree, it's possible with 2 transistors to do the job, I done it too in the past, but anyway, I find simplest to just change The IC.

My challenge now is to do it on my 2 SG503 witch use strange segment decoders.
