WFC Tubes conditioning

[Prophmaji]

chokes, or inductors, when the one end is OPEN, the coil becomes a CAPACITOR, when the pulse is shorter in length (time wise) than the length of the 'speed of transmission' of the coil. Below that frequency, the coil is 'invisible' to the load. This means, that if you need VERY high speed capacitance, that is FASTER than ANY capacitor, you need a large value coil. What you do, is you place it in the circuit the same way you would put a capacitor, ie, the positive to the hot line and then the other end of the cap to 'ground'. In this case, you do NOT close the circuit. You leave the 'ground' end of the coil OPEN, and the other end connected to where you need the high speed capacitance.

This is specific to buffering high speed DC rails in amplifiers of any sort, or a similar application. There will be a resonance. Exploit it.

I don't care what any given capacitor may be like. This is notably faster, when it comes to delivering pulse current.

Thanks for that informative reply Prophmaji. I have seen my power supply voltage go up from 13V to 14.2 with out the inductors being connected to the cell, but in series to eachother while adjusting frequencies... Nothing happens when the are left OPEN though....

Ok, it's been nearly 48 hours of testing my method of tube conditioning and it works!

As I stated earlier I put a large capacitor 3300mfd on the slow section of the pulser circuit, adjusted the mark/space till I got about 20 seconds on time 70 seconds off time, at the start of this process the inside of the outer tubes had rust on them, now they are shiney!, it should be noted that over this period of time I change the water and dry out the tubes so that the oxide layer on the inner tube becomes firmly fixed, the drying process is done over a warm stove gently, if the heat from the stove is too high then the up draft will carry away some of the loose oxide before drying is complete.

Ravi's is one method for oxidizing/conditioning and a good one, but it is not the only method.

ETA: the on current used in the process was 300 ma for my setup at 12 volts, this may vary depending on the number of cells, I only have two.

I have been using 500ma with mine after the flaking accident, and it's working great. I have found out why my tubes were rusting. It's beacuse i let the water get too brown. If I change the water sooner the stay clean. I'm using three tube sets. There has to be a math constant equation to keep it simple as far as voltgage/amps with tubes quantity.

Hi Runningbare,

Seems like you have a pretty straightforward way to do conditioning. I guess I'm gonna try it too when i have my replication done. Can you let us know how often you change water and dry the coating?
