KG7FUR looks like a bogus ad for a Commander 2500 amp with 2 new spare 3cx800A7 tubes.
I believe this guy has high jacked this call. Some research turned up same email address last year
that when the real KG7FUR was contacted he had no adds posted to sell any equipment.
I responded to the current ad and could not get a phone conversation response.
