little dot1+ schematic

[Dagwood]

Trouble shooting a Mk1 version of this little headphone amp, does anyone have a schematic?

Cheers

Here is one I drew years ago. It has notes on mods I made to mine. I hope it helps.

Thanks @TerrySt , much appreciated.

Any tricks to getting the PCB out?

Cheers

It’s been a long time, but probably you have to free the output transistors from the housing.

I was bored, so I opened mine up...
Remove the tubes.
Remove the four screws that hold on the front panel.
Remove the four screws that hold on the back panel.
Lift off the bottom cover.
Remove the four screws that hold in the PCB.
Remove the four screws on the top cover that hold the heat sinks for the output transistors.
The PCB can be lifted out.
Mine is a little Dot 1+ and the pcb is marked as v2.0
