Default Re: Hope to start an audio amp with CV415/CV4046/TT15

Started on the PSU today with a bit of metalwork, mapped out the smallest area I thought I could get away with and a bit of cutting welding and drilling later I end up with the start of the chassis., second picture is the general layout, nothing is connected up as I have to make holes for mains entry and supply out before I start to build it up.

Used 1.5mm mild steel as easier for me to weld as compared to aluminium and the transformer and choke weigh a bit.

Will be using silicon diodes at 1KV PIV and 3Amps max, to minimize Volt drop, but as the caps are 100 and 180 uF thinking of putting a couple of 100 Ohm 5 watt resistors in series with them to prevent the diodes seeing a dead short on switch on.

A hobby that can combine metalwork with electronics and Valves, not bad.
