Hi Bob and Günther,

    First, thanks very much for this great history!  I am always learning something new from you Günther 🙂 

    Out of curiosity,  what are the current Lectron-RWO earphone blocks using in terms of impedance and build materials?

    Bob, I would be very pleased to send you an earphone block for your model 3 rebuild.  Just send me your mailing address by email and I will take care of this at no cost to you.  Do you have the first version or the expanded version of the Raytheon Model 3?

    Welcome again Bob, we are all pleased that you are onboard and look forward to your future contributions.   May we understand how you came to find the Lectron.Info portal? 

    Best regards to all my fellow Lectroneers,
