I would be interested in knowing what arrangement has been used for BA xmitters. My station now has a Globe HG-303 and/or Globe Chief 90A and a Eico 730 modulator. I hope to use my D-104 mic (Has preamp built into base). Any info re schematics, parts, etc. will be appreciated. TIA 73 Gene, WØQFC Spring Hill, Florida WEB SITE: http://www.w0qfc.com
