Is this a Revision F?

[vacantmindguitarist]

Just got a dual recto. It is serial number R-002566. Is this a Rev F? Thanks

The earliest Revision G I have seen is #2822, so yes your amp should be a Rev F.

To know for sure, unscrew the bottom four screws on the amp, pull out the chassis, and look for a revision code near the 4 big blue capacitors. RF-1F, or something like that.
