Default A Cautionary Tale

I have my EKCO U354 wired to an inline switch so I can turn it on, make a cuppa and listen to 'Today' in the mornings before going to work. On one morning this week SHMBO asked a question so I turned the volume down and forgot to turn off the radio. Returning home I went to switch her on (for PM this time) and found it already on and not working.

The UY85 rectifier had gone short twixt heater and cathode and had been lit up like an christmas tree all day. This melted the case a bit, caused the DM70 heater to blow, two resistors to fall apart and the 100 Ohm section of the dropper to go O/C. Luckily no fire and after replacing the dead bits working again.

I think I will fit a dial lamp.
