    I have an amp thats called a Firebird f100 Swinger 4-Bil. This was my Fathers before he passed, and i know nothing about it. I haven,t found out much about the amp searching on-line either. I know there are qite a few very knowledgeable people here, so i though i,d ask if anyone has any info on the thing. I,ve had it a long time, and would guess it has to be from the late 70,s. This is my first post. Bear with me!

    Open it up and take a couple pics of the inside and post them. Take one of the whole inside and then a few close up of any tubes, transistors, etc. That will help a lot.

    thanks moleculo,
    I took some pics, but not sure how to post them. This ol amp has two 6lq6 tubes. When i key up, it hits about 70 watts driven with my golden eagle m3. It swings to about 185 w . This is with about 3 w key. The brownings are the only thing i have to test it with, although i hooked it to my wifes cobra mobile, at 4 w there wasn,t alot of difference. The amp did dead key more into a dummy load 95 w. Swung at 200 aqpproximately. This is on 11 meter. Like i said, i have some pics now, just not sure how to post them. The amp has a rec. boost which is nice, rf swinger, 10-40 m, bil amp (rec amp) that works excellent, stndy-oper switch, am/fm-ssb/cw. I just cant find any info on it.

    You have a tube type amp that is running; what specific questions do you need an answer to?

    Most specifically i,d like to have an owners manual or a schematic on the amp. As i said earlier it was my fathers. Not really looking to sell the thing; only to learn more about it. Knowledge is power.

    Your amplifier is one of many "Knock-off" amps circa 1970; although the name may be different, they all had the same design. The amplifier has about 800 volts on the tubes and is operated Class A (no bias, all grids grounded), what you see is what you get, don't go trying to squeeze 10 more watts out of the thing, it's a 150 watts box at it's best; tune it for swing on your meter.

    This is a schematic for your type of amplifier, this roadmap will get you any where you want to go inside that amp.

    Good luck

    Thanks Slam Dunk,
    Closest i,ve found yet. And yes i realize it is one of the many variations of amps made in the era, or as you put it, knock offs. I must ask you though, a knock off of what? I,ve never had an amp that is more reliable than this one.

    ABC, Apollo, Kris, Firebird and, Courier were makers of single band amps in the early '70 using the 6LQ6 - 6JE6 tubes; some were multi-band "Amateur" amplifiers. D & A (Delaney and Allen), Maco and, Varmit made bigger amps using the 6LF6 family of tubes. Maco was a large supplier of amps using the 8950/2057 tube in mobile designs. As the 6 volt tubes dried up, Kenrich went to the 20LF6.

    There were monster CB amps in the 1980 made by Telstar and Anderson with Ceramic tubes.

    You had to have a license to buy Amateur Amps at the local outlet so, there were very few new amps on the CB Band around here.

    Thanks NorthStar. It is kinda pretty, ha ha. Funny though, i saved the pics i took the other day in my ebay folder. Didn,t realize that until i looked at them on this forum. I,m not putting it on ebay. Putting it back on the shelf. Thanks to all of you who have helped me with this. Especially for the schematic.
