I have everything for the Quieting the Beast mod except for the 0.33uf, 400V metal film capacitor. Where bouts can one be bought? I tried radio shack and had no luck there. Do I really need this Item?

I am curious about this too. I had hoped to complete the project without having to order from the Internet, but the ring terminals and capacitor aren't available at my local Radio Shack. Fortunately, I found a few solutions. 1) Order the parts from www.digikey.com. Do a search for "400v .33uF" and look at all the Polypropylene Film and Polyester Film capacitors available. I think any one of these would work fine for your purposes - just pick one that's in stock and has a min. quantity of 1. Digikey is just one of many parts suppliers on the Internet, but it is one of the largest. Beware - some sites have minimum orders, and some just charge an extra fee if you buy less than a minimum amount of stuff. 2) Get free samples instead! Molex stocks ring terminals of various sizes and shapes, and they'll send free samples through first-class mail - that's how I got mine for free. Finding free samples of the capacitors is harder, but I sent requests to digikey as well as EICOS and Panasonic - hopefully one of those will pan out and I'll get the part. If I end up getting more caps than I need from my sample requests, you could send me a SASE and I'll just drop one in the envelope and mail it back to you. I'll have to see what comes in though - could take a week or two.

Guys, to this here forum! Yes, you should have the cap, if for no other reason than it's a small price to pay for a large amount of insurance (against possible injuries). Sweating the details now (like finding the stupid cap in the first place) is more appealing than the alternative, no? Fortunately, the exact capacitance value is not critical, but it shouldn't be lower than 0.1µfd. And just because most tube amps use at least 350 volts, the minimum voltage rating should be 400 VDC. Go higher if you know that you'll be playing a Marshall Major or some such (700 volts out of the power supply - use a 1000 VDC rating). HTH sumgai

Or just use RF.

I'm using a Marshall 1959HW, not sure on the voltage at this moment. And to hornpipe2 - Yes! I'll send whatever you need my friend.

went to digikey,.. whoa, great site.
I searched for the ring terminals, the .33uf caps, and audio cables for the shielding mod .. however, I got all these search options, many manufacturers,.. just too much.
Hornpipe, could you tell me which capacitor type did you get? Which ring terminal type? And they also have some audio cables with 2 conductors but i'm not sure which one I should get.
(if you could provide the product numbers, it would be most excellent!)
Thanks.

Hi again, Well, i've already found some audio cable (Two 24-gauge, stranded conductors plus shield) And i've found a site were they sell ring terminals, but i don't know which size of stud to get. They have them from 1/2 to 10 in size. I don't know what size would fit over the shaft of the pots. oh, and hornpipe, please accept my apologies,.. i think i was dozing of when i was reading this "Do a search for "400v .33uF" and look at all the Polypropylene Film and Polyester Film capacitors available. I think any one of these would work fine for your purposes" Ha!... Anyway, I just need to know which size of ring terminal I need for the "quieting the beast" mod. Does anyone know? Thanks.

Sorry, I just posted a double topic....but even with the above mentioned link Im still having trouble...there are just too many options!
What does radial mean? That means the posts are side by side, right? For the big cap I want the posts on each end to make my grounding project easier on me as well as fitment...do I have this right?

Hi, The modification Quiet the Beast needs this item (capacitor) to work? Or is it just to protect the user from a lethal electric shock? If it isn't there then the Signal Ground isn't connected to the Noise Ground (therefore, the strings) in any way... So my question is, does the Signal Ground needs to be conected to the Noise Ground(the aluminium foil, strings, bridge)? And the connection has to be made with a Capacitor (maybe to block the AC signal, guitar signal) or it can be made with a normal wire? Bye!

sonny, Yes, the two grounds do have to be connected in order for everything to work. The theory here is, if you insert the capacitor between the two, you have a much better chance of withstanding a faulty amplifier sending a surge of high-voltage DC into the guitar. Yes, the chances of that are remote, but the fact is, they are there. Being very close to zero is not the same a being zero, where your health and life are concerned.
Strictly speaking, QtB will work as intended without the cap. If you opt to leave it out, connect the two ground circuits using wire that is the same gauge as the rest of your guitar's guts, probably 20 or 22 guage. 24 also works, but it is a bit small.

Ya'll just saved me from a planned wasted trip to radio shack in the morning. I was headed out to get the "400" cap also. In the mean time, All this " Killer hot wire " had me thinking about the old cigarette stuck on the head stock trick, Flip a switch and the bass string turns [glow=red,2,300]Glowing Red Hot [/glow]so you can light your Cig. the same way a cig car lighter works.... Now that would just blow Jimmys lighter fluid "Burning Guitar " right out of the water ....

Incidentally, I'm heading over to Tanner's to pickup some 0.33uf, 400V metal film capacitors. Who wants one?
All I want is a buck. $0.50 for the cap, and $0.50 for postage.

Radial = side-by-side leads [CAP]= Axial = end-leads -[CAP]-
