Here’s a photo review of the Teknetics T2 teardown. It’s an original, not Chinese made, machine. The peculiarity of the T2 unit lies in the fact that Chinese are producing the Teknetics T2 copies that are hardly distinguishable from the originals. It’s also very hard to spot the differences in electronics (but still possible).
Other info about the Teknetics T2 is collected here (news, tests, comparisons, reviews and opinions) and on Knowledgebase pages. There you can find things you should know before buying this device. The experience of others will help you save your time and money.
Thank you for the pictures. How was settings selector detached from the front panel? looks like there is a thread on it for nut.
