Nice restoration! I like your PID box setup and extra fan in the controler!
I'm rebuilding a 2016 Linea 2AV right now.
A Perfect Job !!!
Thanks. Was very happy with the result. Machine is very well built so that really helps. Also all parts are still readily available if needed.

@@dracwong I take care of technical maintenance
Beautiful work @dracwong looking to do a similar restoration, any specifics on citric solution or materials for polishing?
The citric acid bath is around 50% concentration heated to 75deg C to speed the process along. Its a weak acid so even at this concentration its very safe to use. You just need to be really careful with the shiny plated surfaces but I was not fussed. Cleaned out all sections with soft metal brush and pipe cleaner as well. All the brass/copper boiler parts polished with soft wire brush wheel on bench grinder unit. The stainless panels were polished with metal polishing paste on cloth polishing wheels but this was a lot of work. I would outsource the stainless metal polishing next time.
Did something similar.. It cost me the same as the used machine, and 2 months. I wonder what this cost you ?
Most of the cost was in time. All parts were reasonably cheap and readily available. I did get some temp probes made up by a local instrument engineer which was the biggest cost.
@@dracwong I had to replace 5 tubes. A big local cooling company was the only one I could find that could silverbraze copper. And, they did not charge me!! After 10 leaks and other issues under first upstart, I have a 6L HX boiler espresso machine! And I have the knowledge to fully maintain it! But, it was not a first lv restauration like you did.
