I have tried to figure out how to do this but my education lacks. What do p eople like me do when they need something done they can't do ? Pay someone.
I need an audio transformer, actually a center tapped choke. I can't seem t o source it so custom mad, oh well. You get what you pay for.
This has to be high quality for audio, not saturate or any of that and I ne ed a low DCR.
This is the configuration;
Version 4 SHEET 1 880 680 WIRE 256 48 64 48 WIRE 368 48 256 48 WIRE 256 128 160 128 WIRE -32 176 -32 16 WIRE 64 176 64 144 WIRE 64 176 -32 176 WIRE 64 208 64 176 WIRE 368 208 256 208 WIRE 160 272 160 128 WIRE 256 304 256 208 WIRE 256 304 64 304 FLAG 160 272 0 SYMBOL ind 240 32 R0 SYMATTR InstName L1 SYMBOL ind 240 112 R0 SYMATTR InstName L2 SYMBOL pnp 0 48 R0 SYMATTR InstName Q1 SYMBOL pnp 0 304 M180 SYMATTR InstName Q2
The load consider to be four ohms from end to end. I need to push +30 volts into one end and have -30 volts come out the other end, able to feed low i mpedance. I need it to do that efficiently at least from 20-20,000.
How much ? Or do you want in on the deal ? They will go for like two grand so just 5% is a Cnote. If you're any kind of an audiophile I could just giv e you one of these amps. There really is nothing like them on the market.
If you can't get my email with your client software it is JURB6006 at gmail , and of course dot com. You can reply here, just how much do you want to d o this ? I need wire size, number of turns and the core specifics. I know t he basics about transformers but this is beyond me. Frequency response flat and all that, I have no clue. An RF transformer I could tune with caps, a power transformer, actually I tried using one once and the performance was not good.
I used to do this scrapping tube amps that had 4 and 16 ohm outputs with go od results. The 4 is the center tap and the 0 and 16 are the ends. thing is if I go too high in power I am inducing a hell of alot of voltage into the "primary" which isn't really anymore. But it can arc and break down insula tion. I would consider them but for that, I would need them in the higher w attage range. Without the "primary" it should save money and weight.
I have it mostly figured out except this. Well and one thing i want to do t o the tone controls, at the highest turnover frequency the treble will have +/- 20dB range, if the turnover is lowered by the control to boost more of the spectrum I want to decrease the range so people don't blow their tweet ers. I might make it switchable - "treble protection". Other than that over half the math is done and I am all the way back to the tone board, it is d esigned but I want a differential drive to the output circuit.
Interested in this ? I am not hard to find.
