This minimal (partial) kit is designed to be used with any run of the TTSH kit from The Human Comparator.

Unfortunately we are not able to offer the rare parts kit any longer. This is a partial component kit that contains some of the parts needed to build the TTSH – at a discount bundle price. The optional matched transistor pairs were matched using the recommended Ian Fritz method to within 2mV of each other.

This does not contain everything you need to build a TTSH. The PCB and Panel are only available directly from The Human Comparator. The other parts can be purchased from Mouser or Farnell etc. see full BOM and build docs here.

Please note that as this is not a complete kit, Thonk won’t provide build support directly so please consider this before purchasing.

Please use the Muffwiggler forum for community based support and advice:
