Hi,
do you know the responsible IC for the reverb ? The reverb in my cube is dead...
Thanks and regards

Hi!
others similar models, like the old "orange" roland cube, worked with a power IC in the reberv drive. Its works with a OP and dicrete transistors as driver (more universal replacements!) The input reverb coil impedance is 8 ohms.

Hi,
...thanks all. Checked the reverb unit in a different amp and it's OK. Also changed the IC, but no reverb at all. So try to change the transistors Q1, Q2 & Q6 as well and hope this will solve the problem.
