Circuit: | Here's the factory OTR schematickindly donated by Pedro Lourenco Pedro has also drawn the (slightly different)schematic of his OTR80 (2002) |
Chassis layout: | The pics shown above show that Orange uses a standard type PCB for reissues of all the older models.(although the Hustler 125 probably doesn't fit on the board) |
Comments: | ATTENTION: apparently the transformers for the 120W versions are also used in the 80W versions. This means that the output impedances of the OT for the 80W are not 4/8/16 Ohms as it says on the back, but they are 8/16/32 Ohms!!! |
