In Reply to: choosing a tv damper diode... posted by jarthel on April 18, 2007 at 22:11:45:
When the tube damper diodes were made years ago,they were used primarily in television horizontal deflection circuits and they would also supply the DC source voltage to the horizontal output tube plate cap..You need to look up the ratings of each tube but black and white used one type with less current and piv plate voltage and color sets used another heavier type but they were all same principle.
The reason there are so many different types and ratings is every manufacturer of tv sets wanted to be different for whatever reasons..They had octals and 9 pins and 12 pin compactron types but all did the same basic thing.
Pick a rectifier by output current and peak inverse plate voltage..They(damper diodes) actually produce high currents than say a 5u4 and have a higher piv even tho they physically much smaller than a 5u4.Most use two of them together and you will be able to swing a nice steady supply voltage..
The 6dw4 would be a good choice.
