I've been for years to buy one TTI, for years... And you have how many?
I got 4 PSU in the last month and sold almost all the others (I still have an HP 6xxx 20V 10A to sell, coming soon...), here my aim tti family:
QPX1200SP big daddy 750€
QL355 the wife can cook everything 210€
EL183R silent little baby 100€
PL303 the teenager 216€
FUUU over 1K€, and now the LD400P .... scary...
What surprise me I did not even use my mafia channels (well... the QPX1200SP came from Serbia in a truck's friend of friends... everything arranged in whatsapp and I paid cash in an private apartment.... was a high risk move...only italians can do that), everything was in evil bay or the local german ebay.
Pictures are coming soon.
Also big big plus the schematics are available somehow, I think if you ask they send them to you.

My italian mind still can not digest we have nobody here from GB with some "connections" to the TTi guys.
