Little Dot MK2 preamp issiue

Good morning. Hope you all well.

I have got LD MK2 and i'm using it as an preamplifier with my turntable. Haven't play anything for few weeks due to lack of time. Yesterday i came back only to find out there's nothing happening. Sound does not being amplified by LD. Now i know it works as a headphone amp because i tested it. Tubes are well too. Nothing wrong with turntable either. Because it works with other tube preamplifier.

If anything i would say it could be LD because i gave it to a friend of mine for a week and hi could change anything.

I know there is manual but can't sort it out as what switches, those red one, should be set up. Tubes are selected as they should be, using two small black connectors.

Im using ortofon 2M Red as a main cartridge .. .please dont judge 😀

Could anyone with LD whom could guide me what i need to change to make it work as a preamp as it was before ?


Thanks

matt
