Quad 405, home-built mega-Quad 405,



** A Kiwi service tech working in Sydney ( Brain someone ) told me how popular it was to build your own Quad 405 if you lived in NZ. Good copies of the original PCBs were available and clones of metalwork & other parts too. This was in the early/mid 80s when buying a genuine example was impossible or crazy expensive.



Started (not by me) at NZ Railways where I was a comms tech . The main
enthusiast even went to the extent of getting heatsinks cast !



Later on NZ Broadcasting techs also did something similar (not the
heatsinks though).



Like to know some details of you "mega-Quad 405".


Twin c-core transformers, larger reservoir caps, MJ15003 outputs,
TIP42(?)C drivers and 55VDC rails. Better electro's and poplyprop caps
throughout where appropriate.
