Could I use *any* MC7805CT as a replacement, as the first link shows diffe=
rent models of that regulator? Some models of the regulator have variable o=
utput as listed in the second link. I suspect the output should stay consta=
nt for power, but since the amp output section has the pot on it, was wonde=
ring if I should go with the adjustable output regulator or just stick with=
a fixed output?

This chip is a voltage regulator, not the audio amplifier. The part number=
indicates that it is a 5v fixed regulator.=C2=A0

They list multiple models of that chip. The one I think is closest is...htt=
p://pdf1.alldatasheet.com/datasheet-pdf/view/82852/FAIRCHILD/MC7805CT.html
because of the variable output.=C2=A0 The amp does have level/volume pot on=
it. The other datasheets in the list do not show a variable output.

Anybody have any ideas as to what model regulator it is? (or what I could s=
