content: Um, that could have gone better all round...Okay it was very short on technical basics, e.g.1. Audio or Radio Frequency load ?2. Impedance required ? but could have been surmised from AF or RF.3. Max working Wattage ?With the above, I expect you would have been given an answer... however, we all learn by experience and help; it's the box of sparks syndrome.
