Quickie mods

[Doc B]

In my experience glue is never as good as a mechanical connection for caps. The best thing is to use a zip tie hold down that is screw mounted to the chassis plate and strap the cap down to that with a zip tie. Caps are covered with very slippery plastic (polypropylene? polyester?) and no adhesive sticks to it very well.

That's what I originally wanted to do...but that seems like it would be challenging with the caps mounted vertically. Maybe I can screw two vertical brackets to the outside of the back wall of the chassis, and then zip-tie the caps to the bracket...

 

[adamct]

By "bracket" I meant a mending plate similar to this one. I think that should do the trick nicely. I can screw two of them vertically to the back, then strap the caps to them using two zip ties each (one high, one low).

Best,
Adam

This 3M stuff is pretty amazing. I also use it to secure my cables to the wall molding when I have to run wire for a distance. It sticks. For a long time. For me, I'm always screwing with my shit anyway, so its easy to yank it off and put a new slab down when I'm done. I dont have to drill any holes or anything, so I dont have to commit on where the thing is going to stay.

Ok onward and upward... I stumbled onto an awesome realization. Sure, I  know, 'ok Eric you're just fucked up on dope'. Nope, thats not it. I'm pretty flat blown away. This is real. I have liked my modded Quickie now for some time. What I didnt fully realize until the past couple of weeks, is that resistors make a LARGE difference.

I didnt realize that because I did my resistor mods along with several others all at the same time. What I didnt do, is swap out one pair (the 1K's that are in parallel with the electrolytics). The reason was, at the time, I had some good electrolytics in there, and I didnt feel like hastleing with them. Well, many months have past. The electrolytics are long gone, and there sat the two 1Kohm Dales in there (they were the first level upgrade - I later replaced the Dales with Tantlelums). What picked my curiosity is that, on a lark, I subbed in a couple of high quality carbon comps in the 220ohm spot (where they originally were in the stock kit). I was hoping to get some euphony or something. Not sure. Well, that didnt happen. The Tants that I had in there blew them away. The comps just dumbed everything down. Resolution went to shit. Sure they werent 'burned in', but when I hear something that has that far to go, I yank it. Anyway, back in with the Tants. That experience got me back online and I ordered a couple of 1K tants from Parts Express. Now, several weeks later. I'm getting around to listening to some music that I havent listened to in awhile. Good shit homer. Unexpected.

Curious if anyone else loves the Tants? From what I have read about them, most people really like them. What I can say, is they are super clean and resolved. Tight and quick.

Who are you calling tight n quick(ie)?

  Ok, I have tried the tants to change the input impedance of my integrated amp. My view is mixed. More detail, perhaps. More edgey perhaps.
And BTW, I didn't have to use dope to get fucked up,    i was born that way(the dope did make some enhancements though).

I thought this might be of interest to Quickie modders.
They claim this is the largest film cap ever made? 63 volts is good for a Quickie.

I just looked at caps that are even biggger ,by a LOT at madisound. Some crrrazy guy here is using them in place of the electrolytics. They look to be almost the size of coke cans!

 

[adamct]

Interesting. Reasonable price, too. But probably overkill for the Quickie. The v1.1 Quickie only uses 150uf electrolytics, and Paul has said that these can be replaced with any film caps over 47uf... I just built mine with 100uf ClarityCap SAs, and I can assure you that the bass is deep, hard and solid.

Greg, if you were referring to me...I can confirm that the ClarityCap SAs are considerably bigger than a Coke can!  ;D

Best,
Adam

Madisound doesn't sell Clarity Cap TC series.  I haven't found a need to use their biggest cap - 430uF 700V 84mm D x 145mm L  ESR 1.0mOhm    ...not for a lack of trying.  BTW, I use these in a tube amp.  Not the Quickie.

Oh wait.  You're talking about the other crazy guy.

 

[4krow]

LOL  Yah, when I say the CRRRaaaaazy guy, it really doesn't narrow it down much! Don't know if I am brave enough to use those 'cans' for my Q. But then again if Earic tries it I have kno choice(I'm inventin my own language, let's see f it catches on).

  Let me deal with some small issues first and then maaaybe caps will follow.

 

[corndog71]

I was tempted to go up to 100uF caps but ended going for just 51uf instead just to save money.

Here is a 100uF ERSE cap (the big black one!) in my center channel crossover:

 

[4krow]

for a second there, I thought it was Quickie overcome by capacitors ;D

 

[earwaxxer]

I have yet to try the Sonicaps. They are on my short list. Good value. That does look like a cap gang bang!

A little explanation for the new members... You see, Greg and I are, how shall we say, "brothers from different mothers". So if we seem to get bitchy at each other, its kind of genetic. We have shared the same locals yet at different points in time. Greg is a time traveler. He's from another world. We need to be patient with him...

 

[4krow]

Shut up Earic

 

[corndog71]

The sonicaps (Gen 1)  are a good, neutral cap.  Ok, they lean a little on the brighter side of neutral but give very good resolution for the money.

Hi guys,

I am looking at upgrading the output caps in the Quickie.  I am worried about discharging the capacitors.

I have read that you should attack a high value resistor to both sides of the capacitor for a period of time to totally discharge so there is no concern for getting some voltage when upgrading.

I was wondering if the following resistor would be good to use to discharge the capacitors (I would also be using it eventually to upgrade my Crack output caps):

http://www.partsconnexion.com/resistors_amtrans_amra_five_watt.html

I would be buying the 10k resistor and attaching it using alligator clips and just leaving it there for awhile.  After I guess that I should verify there is no charge with my multimeter right?

Any guidance would be great!

Thanks...Dave

 

[earwaxxer]

Hey Dave - dont worry about current/voltage from the Quickie. Thats kind of the point of the kit. You really cant kill yourself messing with it. Well, I should preface that, Greg will probably kill himself working on the Quickie because thats Greg.

Just yank the sucker and move on. I have the Mundorf Silver/oil in at that spot. Pricey but quite nice!

 

[corndog71]

The quickie is not a high voltage circuit.  It's battery powered. 

You're thinking of the power supply caps in circuits with well over 100 volts in them.  In those cases bleeder resistors on the power supply caps is a good idea. 

But the quickie is absolutely harmless.
