Re: Filter Caps Explained

I think you gents need to give a "hat's off" to Jon, He's really passing on good info and for the sake of just sharing it with you! I of course don't give a two shit's about any of you nancy boys! Well thats not true. Again "Thanks Jon!".

BTW...just so everyone is clear...the Major chooses the text color "lime green" because he's truly a "limey brown nosin' wanker" at heart.

Once you clip the jumper in place, you can verify that the caps are discharged by measuring voltage at the HT fuse socket. All of the filter caps are connected together through the dropping resistors in the amp so clipping the jumper between pin 1 of the first preamp valve will discharge all of the caps through the dropping resistors in the power supply and the jumper to ground from pin 1.

As I mentioned in my previous post, this is how us amp techs discharge filter caps so if it didn't work, why would we do it, let alone recommend it to others? It works on every valve amp and is the absolute simplest method.

Not to sound rude or anything...I say this solely for the sake of personal safety, but if you're having trouble visualizing why this method works, looking at a schematic of a 2203 (or any valve amp for that matter) should spell out for you why it works. If you can't figure out why it works by simply looking at a schematic, then you probably shouldn't be poking around inside of an amp containing voltages higher than your wall voltage.
I'm probably going to disgust some of the "all tube" Marshall fans(have mercy) for chiming in here, but hoping this cap info might potentially help protect me....,......... will the same discharge method work with a Valvestate amp for discharging caps by jumping gnd to pin 1 of ECC83/12AX7 preamp tube......I'm "also learning" and successfully repairing(mostly working on 90's Valvestates(8100, VS100, VS65R, VS265.....sound is good for some applications).....

I do have tube JCM900 SL-X(working great) and JCM2000 TSL(need to replace, or resolder footswitch DIN connector on PCB).......

Listen hear you empty headed animal food trough wiper of other people's bottoms, "political correctness" is a ludicrous statement from the beginning!
