1. [Amps] AL-811H on 6m (score: 1)
Author: "Crawfish" <crawfish@surfmore.net>
Date: Tue, 10 Aug 2004 21:43:09 -0500
One of the folks on VHF Contesting list is wanting to put his AL-811H on 6m. I told him that 2 each 811A's would work, but IMHO, the output capacitance would be too high to work on 6 with all 4 tubes
