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.

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
