Aikido cathode follower (ACF) with 12au7 | diyAudio WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES. I purchased from Glass-Ware.com an Aikido Cathode Follower 2 (ACF-2) All-in-One 9-Pin PCB, designed by John Broskie, the editor of Tube Cad Journal (tubecad.com). This unity-gain buffer, using a modified cathode follower, offers a high input impedance, a low output impedance, low distortion, and a great PSRR figure. With a twin triode, V2a and V2b will be balanced, and the output will rest at B+/2. Okay, that was how it works, now we move on to what it could be used for. :| Aikido Cathode Follower - Tube747 23:45:01 02/13/21 (0) RE: Source Follower vs Cathode Follower - Eli Duttman 12:10:35 02/13/21 ( 0) RE: Source Follower vs Cathode Follower, posted on February 13, 2021 at 08:59:25 Jack L Log in or register to post comments If you’re like me, you’ve wondered if these can be any good at all – or just a waste of money and time. (Glaseware Audio/Aikido) « Reply #8 on: 21 Feb 2014, 01:40 am » Hi Anand, it was the octal all-in-one kit and there was one mistake on the location of resistor R22/23 on the PCB if I remember correctly ...and a couple mistakes in the manual. In other words, the ACF-2 is a unity-gain buffer for those who do not need any extra voltage gain, but do need more current delivery than a passive line stage would allow. Duplicate 70: Aikido Cathode Follower [ACF] Born from the rib of the two-stage Aikid... 3.3% of the text are stop words. Location: Northern VA. for a 6n1p preamp, I'd use a 300-350 V B+. Each channel uses one half of the output tube as a cathode follower. A simple, textbook cathode follower consists of only two key components: a triode and a cathode resistor. The typical Aikido circuit (there are many variants) has a two triode voltage amplifier section, and a two triode cathode follower section, both utilizing John Broskie's optimization tricks. Well, much like the earlier circuits, we add a capacitor-terminated resistor, but this time it terminates into the B+ connection, not ground. A place for discussion, news, reviews and DIY projects related to portable audio … If Jadis designers would copy Aikido linestage design : anode follower (1/2 ECC833) + cathode follower (1/2 ECC82) as output tube, the too low load impedance should not be an issue, IMO. The cathode follower operates with 100% negative (voltage) feedback, which makes it exceptionally linear and minimises the output resistance. I received a pair of Amperex 6DJ8/6922 gold-pin tubes, and I've been perusing the web looking for something to do with them. Forum The conversation begins and ends here.

Aikido Cathode Follower Version 2 [ACF-2] Here is one of the new PCB designs that I mentioned here before. The cathode follower takes great advantage of the triode’s inherent degenerative local feedback (therefore, unity gain). Yes, I was half aware of the gm thing in the Cathode Follower, which is why I asked really. This response makes a lot of sense, as the cathode follower offers a gain close to unity, a low output impedance, and low distortion figure. This is relatively uncommon with OTL headphone amps, which usually get along best with headphones ~300 ohms. 15: Aikido Cathode Follower (8.43) Posted by Tube747 on 2021-02-13, 23:45:01 (202.40.157.165) If Source Follower is not adequate, what about Aikido Cathode Follower?

Posts: 284. Exceptions to the cathode follower stage include the White Cathode Follower or Aikido Cathode Follower variations, and the SRPP. Keywords used in the page title are also used in the page content. where the "Aikido Amplifier" name was coined, ... by injecting the same amount of PS noise at the top and bottom of the two-tube cathode follower circuit. The Aikido injects B+ power supply noise out of phase into the signal to cancel. I also need to replace R15 with a jumper (because I configure this Aikido as White Cathode Follower). Adding cathode followers that DC couples to the grids is the obvious solution, but it also brings extra cost and power-supply requirements. Obviously, I would be a preamp/head-amp usage preference, as I prefer the sand in my output stage. Bluebook The right price. If you build your amplifier point to point, you could try both configurations. with a 15K would be a good start for the plate load resistor. I found a schematic for an Aikido front end driving a White cathode follower so I ripped out the old circuit, keeping the regulated 300V power supply, and just built it. Za vikend sam malo merio ovo čudo (Aikido Cathode folower sa 6N6P, pojačanje 0,95). by Steve Graham. Aikido preamp, naravno, nije SRPP konstrukcija.Prve dve triode cine standardan grounded cathode stepen - "donja" trioda je pojacavac a "gornja" radno opterecenje, vezana kao CCS.Drugi stepen je cathode follower gde je "donja" trioda CCS i tu je upravo primenjena ta cuvena fora sa injektovanjem ripple-a iz napajanja radi ponistenja prisustva istog na izlazu … Hybrid Headphone Amplifier In blog 231, I described the Aikido SLPS headphone amplifier, which used a variation on split-load phase splitter to produce a low-noise tube headphone amplifier that could work over a large range of load impedances, unlike the SRPP or White cathode follower or SRCFPP circuits, which must be optimized to work into a single fixed load … Show us the circuit? Now, how do we add some Aikido mojo, so we can enhance the PSRR? Exceptions to the cathode follower stage include the White Cathode Follower or Aikido Cathode Follower variations, and the SRPP. With a twin triode, V2a and V2b will be balanced, and the output will rest at B+/2. Watch for FREE over 100.000 Indian xxx videos. Evo dok se vode neke besmislena rasprave ja sam bio malo vredan. Here’s the Aikido magic: Any power supply noise is AC coupled through C4 to the grid of V2b. Simon's C3g phono using the front-end I did for him and an Aikido he selected for the back-end is shaping up nicely, now that we have debugged the C3g. The enclosure is from Modushop with front and rear panels custom made and engraved by Front Panel Express. The Morgan Jones designed "EarMax" is an example of White Cathode Follower OTL Another departure from the Marantz original is the choice of signal tubes. These are still relatively inefficient ways of driving a headphone, but at headphone levels, inefficiency isn’t a huge problem. The first is that this two-cathode-follower Aikido version will draw more current; second, unlike the first Aikido-pentode circuit, this circuit is tweaky, which means that we must fiddle with the resistor values. In addition, the Aikido cathode follower produces lower distortion by using the triode’s own non-linearity against itself by providing a complementarily non-linear load for the top triode’s cathode. If you’re like me, you’ve wondered if these can be any good at all – or just a waste of money and time. The PCB holds a pair of cathode followers, each loaded by … NIXIE. Cathode Follower WD Other Parts and Projects. If Jadis designers would copy Aikido linestage design : anode follower (1/2 ECC833) + cathode follower (1/2 ECC82) as output tube, the too low load impedance should not be an issue, IMO. The Aikido pre certainly appears to perform well (from John Bronskie's measurements), but do we need this much gain these days - the Aikido gives roughly 1/2 the mu of the triode in the first stage, so even low mu valves may give the "full volume at 9 O'Clock" problem. If Jadis designers would copy Aikido linestage design : anode follower (1/2 ECC833) + cathode follower (1/2 ECC82) as output tube, the too low load impedance should not be an issue, IMO.

If Jadis designers would copy Aikido linestage design : anode follower (1/2 ECC833) + cathode follower (1/2 ECC82) as output tube, the too low load impedance should not be an issue, IMO. So externally it's identical, with the same tubes, but with a completely different circuit underneath. I had also built an audio switch (4 in, 1 out) with the help of 'buildanamp's' LDR switch that also contains a Glassware Aikido cathode follower in the audio circuit before the signal continues on to a switched headphone plug (with the ground signal grounded to the chassis through a 150 ohm resistor). 464k members in the headphones community. The enclosure is from Modushop with front and rear panels custom made and engraved by Front Panel Express. The input section is not part of the ACF circuit. It has been in my system continuously for that long because it sounds so good. We’ve all seen the ads on eBay for inexpensive PCB’s from Asia, sprouting tube sockets and a few other parts for about $60, tubes included. (Many audiophiles would sooner fetch moon rocks than figure out new resistor values.) This was in comparison to my two-chassis, tweaked-out Aikido line stage. 2 Aikido Cathode Follower 2 So what is required to make a good tube-based unity-gain buffer? Merch Rep the community and hobby you love so much. Finally, he finishes by eliminating the Mu-follower, and restoring the SRPP as a 1st stage + Cathode-follower, complete with a capacitor 'voltage-divider' to inject PS noise, back into the 2nd stage, just as in … Reading Richards post I found the TX pre harsh sounding in my system, the passive was OK but weak, the CF did it for me, no gain is not a problem at all, I lived with this set up for a long time but changed to a kit from Glassware, the Aikido CF, this is basically a CF with active load but with significant … 1878 paragraphs were found on this page.
