Hello,
I have 2 questions if anyone can spare their time. (I'm very much a novice so apologies if these questions are very basic)
I believe I've encountered a broken phototransistor on a stereo system I'm working on and I wish to replace it.
I've never replaced a phototransistor before and the one I wish to replace has what looks like black sealant on its rear and also on the circuit board.
~ I've attached a photo. The broken phototransistor is on the left. The one on the right is working
My 2 questions are...
1. Can anyone tell me what this black material is and do I need to reapply it when I replace the phototransistor?
2. I'm very unfamiliar with phototransistors. The one I wish to replace is model PH101. But I'm having trouble sourcing one. Can anyone suggest a modern equivalent? The Voltage in is approx 9.4v and it must be able to detect light from a standard white LED.
Thanks,
Daniel
