Hello at all.. im new to this forum and also a noob in electronics.
this year i startet to build a diy eurorack.
I found this stripboard layout Called " system 100m lfo" but no further information . it looks pretty simple so i build this last night.
on the first try in eurorack it wont work . so i decided to power it from 15 v bipolar diy supply to make some measurements. maybe i didn´t had enough sleep because im not sure if i make a short between two legs while measurering. but after 20 -30 seconds the tl072 was fried.
now im not sure how to go on with this circuit. it would be nice if someone could look at the circuit and tell me if it could work or is it absolute useless.
greets
markus

in my opinion this circuit has nothing to do with system 100m. the roland circuit is much more complex.
what i want to know about this circuit is: is it able to run or is it crap.
because i´ve allready made a frontbracket.
or can someone suggest me another simple lfo for 12v power supply?
