Orange Dual Terror just had a broken input jack. This amp is switch-able for 7, 15, or 30W and it sounds pretty nice. As far as I know, it is basically just the big brother of the Tiny Terror, having two channels rather than one and having four EL84s in the output section for 30W instead of 15W for the Tiny Terror, which only has two EL84s
Unfortunately you have to disassemble the amp completely including removing the tubes to work on it since most of the solder connections are on the underside of the board. There is one single PCB that has the whole amp on it including the tube sockets. The on/off switch and the speaker jacks need to be removed to make enough room to lift the PCB out.
Doing a very symetrical ~44V pk-pk into 8 ohms for 30W power.
Re-assembled. Could never find the schematic on this one.
