Seeking some info on Allnic L-3000

Before buying a piece like that used, I would find out where it can be serviced if something breaks. It’s not easy to find a good tech who has the schematics. 

@audioguest4life, I know...before I made the first post I searched high and low for the receipt for the L-3000 but could not locate it and I still have no idea for sure what year I purchased it. I do know that Albert Porter was still active on Audiogon and he had to order this unit for me from Korea. Who knows, maybe it's time to replace tubes but the music still sounds very good in that system.

Could be 2016, maybe older?

I appreciate all the info gents. Unfortunately it doesn’t look like the planets will be aligned for me on this one. I’m a bit disappointed, as these pieces don’t show up often. 🤷‍♂️
