Hi Aron,
I just had a look in my regulator draw looking for
MC1468 and found some MC1438R, but I thaught I would check first....glad I
did ! they are op-amp power boosters !, moved them to the correct draw
:o).
I have the Motorola regulator handbook with the
MC1468 in...which package is it in, a round one or a diamond shape chunky one,
or even a dual in line? . It doesn't really matter as the current output is
100mA for all packages, but if with 7V across ( a guess for your other post) at
full load that is about 0.7W. If you have the space put in the TO220 version of
the regulators you mentioned.
Please note that the tab on the LM7915 is NOT
ground, I have been bitten by that one so I thaught I would pass it
on.
I you have the manual or can trace the
circuit, it might be worth checking that there is no facny current limit
employed, the MC1468 supports quite a lot of features. Google will find you the
datasheet if you don't allready have it.
I hope this has been of help, no insults on
knowledge intended.
Best of luck, I would like to see pictures of the
outcome.
BTW I built a synth a few years ago have a
Google for ETI4600.
Cheers
Paul
