I am wondering if the power transformer has enough reserve to supply 3 or 3.75 Amps from the 5V winding. I am looking at higher current rectifier options but they all draw more Filament current. I have Rick's copper cap on order but it is stuck somewhere in the snow and I don't have a TDR yet.

The 5 volt AC rectifier filament winding on the VTA ST-120 power transformer is rated at 4 amps.

Awesome. 5AU4 looks to have higher current rating.
