I've salvaged a MOSPEC F12C20C Dual Power Rectifier from an old PSU. I've been looking for example circuits that would use this component, and an explanation of how it works but I've only found and not much more.If I understand correctly, its function is to rectify an AC current to make it DC, is that correct? How is this different from the typical? (power dissipation capabilities maybe?)According to the datasheet, this component is the equivalent of two diodes package together, is that so?
3 Phase Diode Rectifier
If that's the case, how is it that it can achieve rectification with only two diodes and not the usual four?Do you know of any example circuits I could build on a breadboard to test this component and play with it so I can better understand how it works?Bonus: mine has the letters MNB next to the diodes schematic it has on it. Is it part of the name or is it just a serial number or something?Thanks! You can use this as a if you have a centre-tapped tranformer:– Schematic created usingThe maximum current depends on how good a heat sink you have, but several A are not a problem with a small heatsink, and the maximum AC voltage would be more than 50V (the PIV rating is 200V, so if everything was perfect 140VAC would be okay. The output will be `1.414 times the input voltage AC minus a bit for the diodes, so a 12:12 centre-tapped tranformer (24V from end to end) would give you about 16VDC, give or take depending on capacitor and load.
Best is subjective.It's brighter and tighter than the old 3 channel. Which some people like. Others say it's too tight and they prefer the sag of the old one.Can't please everyone.Myself, I like that it has the ability to assign power and rectifier tubes by channel. So channel 2 can be vintage and tube rectified while channel 3 can be modern and diode rectified. I also like that you can drop the clean channel 2 50w/tube rectified to give it some natural grind and bounce. Much better than the stiff ass clean you get from 100w/diode.They also re-worked the raw mode so that it's not as dull/murky and gave it the Lonestar clean circuit on channel 1.
Makes it more useful IMO. Click to expand.I think it's the best Recto ever.While I was never a Recto hater, the original had problems. The very average clean channel, parallel effect loops which was problematic, popping sound when switching channels, flubby low end and lack of clarity (the original didn't always cut in a band mix), and the occasional 'buzzy' preamp tone. (Granted, many people like some of the above features.
Not me).The new Dual fixed (or at least addressed) all of the above issues. I recently went shopping for a new amp. After playing a TON of channel switchers (some costing over 3g), I went out and ordered a new Dual. I think it's the best Recto ever.While I was never a Recto hater, the original had problems.

It is loaded with so many tones, and I find it way better than the older rectifiers I have owned and played. Crazy amount of tones in this thing from clean to classic rock to metal. So may optionswith the 50-100 watt switches, spongy/bold, tube/diode, 6L6/EL34, etc.I don;t really hear the fizz like I used to hear with my previous few Rectifiers.I had a Recto from the early 90s and another from 2003 and my 2010 is easily the best of those I have owned, IMHO of course.A nice thing about the new DR is that I am not a metal guy but this thing does classic rock better than most amps I have owned. I could spend all day in the Raw mode.
