QUAD 405 Mods

[kayjay]

I have just finished modifying my 405 by making a few changes/additions to the circuit, beefing up the power supply and adding a new protection/ delay circuit.
The results are outstanding and I would wholeheartedly recommend all 405 users to go in for it.
If anyone would like to have a go at it I would be only too willing to be of assistance.
