Zhongxia S66E Six Transistor Radio Kit
Very nice little AM radio kit - a little bit easier to build than the Boshi HX108-2 (Red Case) I offer for sale - there's fewer capacitors and resistors and no diodes in this design.
The 3 Tuning Inductors come pre-set at the required inductance - so no need to tune, I assembled the kit and to receive UK stations I only have to slide the tuning coils up and down the ferrite bar a little for strongest signal - no need to touch the adjustment slugs of the inductors.
Kit comes wioth all components sorted and resistors identified. Original Chinease Instructions - together with a translated version BUT I do offer via email my own build instructions that contain build tips and lots of photographs I took during my own build.

Reviews
I was initially impressed with this kit - the effort that had gone into packing components in separate bags, laying out of resistors on a printed page against their values, and the comprehensive instructions.
However, I was disappointed with the quality of the PCB - in 5 places, the track pad around the component lifted from the board on soldering, and I resorted to using short wire offcuts to bridge connections. I do not believe my soldering technique was poor. It did not work as a result.
