As the KPA 500 uses a linear PSU there obviously is a mains transformer within the cabinet. I know this is a toroidal type transformer, which is good, but can we assume that placement of the Amp with respect to the K3 is non critical, for magnetic hum coupling.
How immune is the K3 to this effect? Has placement of the KPA 500 w.r.t. the K3 been tested for any ill effects? 73, Deni F5VJC On 11 May 2011 07:49, Henk Remijn PA5KT <[email protected]> wrote: > Can we see some pictures of your setup? > > Henk PA5KT > > Op 11-05-2011 4:14, Dick Dievendorff schreef: >> Just for operational convenience I'd consider stacking them the other way, >> with the K3 VFO A knob at a convenient height for tuning and the amplifier >> above the K3. >> >> I've found some very handy open-shelving bamboo "shoe racks" at CostCo that >> are doing the job for me.
