Amps are very low power so high efficiency speakers required.
Lots of foo components AN silver resistors - Mundorf caps ,silver wiring ,CLC power supply will come with a pair of Sjostrom DCT03 DC filters which I definitely think help with sonics and the dreaded toroidal hum.
Got lots of build pics if required.
Oh you’ll also get a spare pair of the original SIT 2SK82 KD33 transistors .
Dare I say they’ve also got AMR gold input fuses
had lots of help with the original build from Pete when on WigWam
