Quickie mods

[4krow]

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!

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! 

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.

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.

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:

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

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...

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):

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

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!

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.
