Luxkit / Luxman A3550 Assembly Manual

[frend2001]

Hi,

I have just pulled trigger on this marvelous piece of tube amplifier engineering.

I can't find a service manual or assembly instructions for A3550 anywhere.

Would it be possible if someone can share it here ?

Only found the 3500 manual, maybe that will help.

Thanks for sharing @rayma

But A3500 and A3550 are totally different designs.

Hope someone has a copy.

Not that different topology, mainly just a minor change in the driver circuit.
