What will you use for an inductor in the output filter following the second transformer? wrote : I had a little time yesterday and opened up a PC power supply and brought the 3 taps off of the transformer out to binding post. The plan is to build a transformer that will step the voltage back up to about 800 volts or so, enough for my little 6146B 6M amp. Jimmie.- Hide quoted text - - Show quoted text - Like you said I like to Frankenstien things. I have a filter from another power supply but I am not sure how well it will work as it was designed for about 25 amps. Basically thats a bridge I will jump off of when I come to it. Right now I am having enough trouble finding an old PC power supply I can get a transformer from. Its hard to believe about a couple of months ago I tossed about a dozen of them. Last time I listen to my wife. I do have a couple of transformers from some old Lambda power supplies. Thes are some really nice ones probably capable of handling a couple of Kwatts. Im not ready to experiment with them yet. Although this is learning by destuction it's cautious destruction. I will probably take a trip down to the local computer place this weekend and do a little dumpster diving or make a run on the goodwill store and see what I can get for $10. IF you havent figured it out by now I love building things from others discards. When I was in high schooI I built a killer stereo, I thought at the time, from old stuff I found in the dump that was the envy of most of my friends. Ive enjoyed doing it ever since. Jimmie Jimmie |
