Hello, I need confirming if this is the Orange Terror Bass 500 MK2 Schematic \, see attached.

That looks like a Mk1 to me. The Mk2 uses one 12AX7 and one 12AT7. Note the preamp schematic shows two 12AX7s. Mk2 has a clean switch...do you see it anywhere on the schematics?

Also, when did the Mk2 come out. The schematics are dated 2009.

well that is why I am asking, sent an e mail off to Orange to get the correct one.

Doubtful they'll send one, most manufacturers don't send them out to end users, only authorized/qualified repair facilities.

Would be interested in what exactly is different though. Seems the preamp is mostly the same outside of the clean switch. The power amps were the issue on the V1 amps if I recall correctly.

I'm trying to repair one of these, not sure if MKI or MKII...

Works up to the fx send receive and I want to drop a new power amp module since I think that's likely the best solution.

No signs of magic smoke, only thing I see is the PCB mounted connector for the fan on the power supply left the board for the male connector... But leads are intact.

Hi BassBeginer64,
Re: your post from May 28, 2024 ref: ORANGE LITTLE BASS THING MKII schematic,
Is there any chance you could let me have a copy, as I have a unit in for repair which I could do with a little clarification on, I have emailed Orange, and have still had no response either way after a month!!

Thanks for your help.
