List, I bought one of them for several reasons besides that I really wanted it. 1. There is plenty of real estate to install Paul’s demod circuit. 2. It is large enough so the nuvistors can be replaced with dual gate mosfets (I have lots of them). Also sometimes replacement nuvistors can be obtained on ebay for a reasonable amount. 3. If needed, I believe most of the divider circuits can be relatively easily replaced with IC’s. However the first thing I will do before firing it up (figuratively or literally) is to replace all the electrolytic caps. I’m not interested in buying the antenna as there are numerous vlf antenna circuits with preamps for 60 KHz on the net. One suggestion I found interesting was the idea of filling your tubing with wet sand then using a truck tire to bend the loop. Where to borrow a truck tire? It didn’t say. Regards, Perrier
