Alan, you could have taken the words out of my mouth. I have been pondering exactly the same question with regard to the RX side of a recently acquired TR4. Anyway, you can be sure of getting an amazing amount of help from the guys on this net and I will look forward to hearing the advice you receive. Nearly 40 years ago I had a R4A. Fabulous receiver.
