i thought about 250€ for the mono kit (working), 200 for the other two (each). I can add a 2U enclosure case in black without frontpanel for 25€. The lundahl transformers alone cost more than 120€ a pair.
hey, this is the one mono unit that is tested & working. the other two channels are made for stereo use but not fully wired or tested. only the components are populated. but they look the same.
