Remember vacuum tubes, you know, the things which have little heaters inside? When I was in high school, we had no trouble coming up with them, sockets, chassis, power supplies, butterfly type variable capacitors for push-pull tube RF amps, and all that jazz. I'm working on a project where I need these kinds of things, but they are pretty darn near impossible to come by. (I'd prefer tubes because constructing VHF solid state class "C" amplifiers is expensive...I expect to blow up more than a few active devices in the process...) Somewhere, sitting in someone's basement, there e ssits eexactly what I need: a chassis, with several stages of push-pull RF amplification, preferably at 6 meters. A power supply is not required but would be nice. Total power output should be in the 10 - 30 watt range but I will entertain others. This device will be employed in a project which WILL have the blessings of the FCC before being put on the air (it will also be modified). I will consider single-ended gain but would prefer the former type. One-tenth watt driving power is available. Of course, if you have a **real** commercial FM transmitter of the 10 watt variety, I cn use this too (or exciter). This would have to be of the direct FM type. Please indicate if you have spares for this device. Again, I emphasize that the project will be FCC licensed under part 74 of the Rules and Regulations, and is absolutely not to be used for illegal purposes. I'm not trying to cop a CB linear or similar device. Supervision will be by several general class operators and highly sophisticated equipment; again, this is strictly on the up and up. Owners of suitable equipment, please state what you would have to have for it, and contact me directly via UUCP or snail mail: David Anthony Chief Development Engineer DataSpan, Inc ( decvax, akgua, philabs ! mcnc !unccvax! dsi) 7853 N.
