[Elecraft] K3 Power Supply

[Geoffrey Mackenzie-Kennedy]

Thom,

The power supply used here for several years with rigs of similar power
output as the K3/100 is a Diamond GSV-3000, which is a 'linear' type (large
transformer!) not switching.

Input    :   230v AC  50 Hz   (There is a version for your line voltage @ 60
                Hz)

Output  :  1 to 15V DC, adjustable using a front panel control.  30 amps
                continuous at 15V,  35 amps maximum (CW/SSB)
                Two auxiliary outputs rated at 6 amps.

Meters  :  Two -  DC Voltage supplied and  DC Current drawn.

Cooling :  Fan, VERY quiet if you can hear it.

Physical :  Colour - black.  Weight - 9 kilograms.
                Dimensions - 15 x 25 x 25 cms (H x W x D).

My K2/100 sits right alongside the right hand side of this supply separated
by roughly 2 inches, and the K2's VCO without the VCO mod kit is not
affected by this power supply.

The usual disclaimers apply.

73,
