In this article I will show the initial construction steps of single ended 45 mono amplifiers which I was requested to build. The amplifiers will have a directly heated driver stage which can be configured to use either another 45 or a 10Y.
These monos are meant to be used with the D3a phono stage which I introduced in the previous article. They will share the same chassis concept. This is the top plate which carries the tubes, capacitors and transformers (Tango XE20A output and NC20F interstage):
The signal wiring and grounding arrangement:
The remaining parts are mounted on sub modules which will be placed inside the chassis:
Stay tuned for an update as these amps get finished
