This listing is for a recently built DIY Nonlinearcircuits FK1T VCF. I've racked it with washers and used a few times to test. Its calibrated and fully functional.
So far Ive built about 15u+ at 84 hp of NLC modules so this has been built well and with care. Will ship out next day Priority Mail with full insurance. I guarantee my work and will, of course, accept returns for any problems related to the functionality of the module. However, I will not accept returns for buyers remorse. Comes with power cable. Please feel free to ask questions.
