Vintage Synth Repair

actually, that's still helpful news. i wanted to have a spare 15/-15
"bench" PSU for testing, anyway, so i might still replace the parts on
the old PSU. so, the tip120 is equivalent to mje1100, do you know what
the mje1090 is equivalent to? and sorry, i hate to ask this, but do
you know the equivalent to the 748 voltage regulator? the mouser part
comes up as 8 pin, which isnt right. thanks alot for the help,
mariano! this is actually good news!

TI equivalents like the tip120, only has to reverse the leads since
their pinout is different, something like TIP120 ECB while the old
mje1100 is BCE... hardly hard to do...the tip's run for $ 0.69 locally
at BG MICRO... this I just found out last night... wish I had known
before you spend your money there...sorry... :(
