WebMay 24, 2024 · A well designed 'White Follower' should not give any untoward artifacts. One thing to mention: the White follower in the LA-2A is NOT one to copy, that top resistor is far too big a value for the gm of the 12BH7 as used. There's lots of discussion online on how to properly design one with the correct amount of signal voltage being sent from the … WebCathode Follower Output6SN7 or 12BH7 Dual Channel. Vacuum tubes are high impedance devices. This can be a problem when connecting a pre-amplifier device, such as an audio control or mixer unit, to a power amplifier or other device. If you use the plate output of a stage to couple through a cable, the capacitance of the cable can cause a ...

WebSep 1, 2011 · In the 5F6-A, there is an extra unused triode if you don't include the cathode follower. In AB763 amps (with reverb and tremolo), you already have 6 preamp tubes. We'd need to add yet another to include a cathode follower for the two tonestacks. In general, there are only a few reasons to use a cathode follower: 1. You need a low output ...

WebJun 23, 2005 · Basically, this is to be a cathode folower with a volume pot for use as a unity gain preamp. I decided to use a 6dj8 as the tube as I happen to have a bunch of them, … WebThis is simple Ohm’s Law. In a cathode follower, the grid is still negative relative to the cathode and this still allows it to modulate conduction through the tube and the load. But in a cathode follower, the load is at the cathode instead of at the anode. The grid cannot make itself less negative relative to the cathode because it is this ... WebThe ACF-2 is an All-in-One design that holds both the B+ and heater power supplies and two Aikido-ized cathode followers. 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. The ACF-2 uses a bipolar power supply and two ... quickbooks time tracker replacement
