Bought an older FLdx2000 a couple months ago. Everything checks out Ok with this amp but I'd like to wire it for 220V. THe manual says it'lll run on 220V but looking at the schematic I'm stumped how to do this. Anyone have any experience with this amp who can help?


THanks!

Looking at the schematic, it looks like you would want to wire the two 110 volt primary windings in block A in series. You would wire the primaries in block B the same way and then feed the two blocks in parallel across 220V AC.

Does that make sense? If not I can draw it out for you.

It is also important to make sure that you wire the series primaries IN PHASE.
