Thank you for your response, I see I had a typing error in may question. I was wondering if any of you folks know of a resource for the old magnetic style earpiece. I do understand how the earphone is used in the amplifier stage as DC coupling, clever use of the components available. I need a replacement for my Lectron system. I have spent a number of hours searching for a 300 ohm magnetic replacement with no luck. I have found that there are times when things like this may be available on the European market and less available in the US such as the 6 V 50 ma. E10 lamp. I have more details about my efforts that I will share later. I have just recently discovered this portal into the world of Lectron and I look forward to exploring.
