Denyo Ceramic Stand-offs

In most hardwired valve power amplifiers it is frequently difficult to get the HT and heater rails properly suspended and separated, safely and neatly from the chassis, this especially applies when building amplifiers using the really high voltage directly heated triodes like 211, VT4-C, 845, 849, 304TL, DA100 etc.
When planning design like this, it is important to incorporate suitable layout from the start, and the Denyo stand-offs should be more or less mandatory in that context.
