Fixing a 100 years old potentiometer (PWJ230)
On my Saba radio from 1927, all four adjustable resistors are bad because of corrosion. So I went one step further to make the radio (hopefully, probably) work again... These resistors are there to adjust the heater current of the four tubes. For example to adjust the output volume because there is no volume pot. Please watch the SABA video PWJ227 for more details about the radio...
