TTSH Rare Parts Kit

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

This is a partial component kit that contains the harder to find parts for the first revision of the TTSH project. The things you won’t find at Mouser, Farnell, Rapid or the parts which require matching to millivolt tolerances. 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.
