005 Dansette Major Deluxe 21, Single Stage EL84 Single Ended Circuit
This is a very simple circuit which is a single ended design using a single stage EL84 Pentode valve.
This is very common for a lot of gramophone units from the late 1950s to early 1960s.
The Dansette Major Deluxe 21, Deluxe Mark 2 & RG30/31 Models often have very poor quality mains isolating transformers. These should be upgraded with the modern type and also fused.
