[Elecraft] OT: Transformer oil in DL's

[Geoffrey Mackenzie-Kennedy]

The Cantenna was introduced sometime between late 1959 and 1961 if I 
remember correctly, without the oil which had to be provided by the buyer. 
Either 'Transformer' or 'Mineral' oil was used by most people who had bought 
the Cantenna back then.
