Ampeg PortaBass800 - need schematic

[dmeek]

This one is making noises after warm-up. A schematic would help a lot.

Thanks

You are going to have to contact Loud Technologies.

They are pretty good at filling schematic requests.

Try to use the preamp schematic.

But I think that the blower and freezing spray will be much more useful.

Thanks Jazz P and Doctor. Loud will be sending me the schematics but it might not help.
The noise is coming from the power amp which contains a large epoxy block module.
They tell me parts are not available for this model. The worst thing is that it's not
heavy enough to make a good boat anchor!
