Upgrading Caps
- Thread starter markc2

Everything in the Quickie can be upgraded! Thats the beauty of it! The only limit is your pocket book, and your due diligence to research what said changes could make.
I would suggest you do a good search for 'Quickie' and 'capacitors' in the bottlehead forums. Much good discussion there.
Caps are a huge field of specialization for the audiophile. We each have our favorites. Most of us have stayed 'sane' in the kind of money we have put into a $99 kit. You can very easily spend a few hundred bucks on caps for the Quickie. I have found the expense worthwhile, in taking a good, but 'inexpensive' sounding stock piece of kit, to a real player in the tube or SS preamp catagory.
With that said, or course you now have the 300b pre to tantalize you!
Here are some cap reviews to wet your whistle!

If you go to the Quickie folder first you only have to search for "capacitors."

Has anyone tried bypassing the high voltage battery bank? There is no special reason to believe that any battery is "better" than a good audio capacitor. You don't want an electrolytic; they do have some leakage and will drain the battery even when switched off, but a nice film cap could well have an audible effect. Personally I'd try 50uF, but I think as little as 10uF would be effective - if there is an audible effect.

I would suggest attaching film caps across the tubes from the incoming "high voltage" to the circuit common, below the cathode cap and resistor. The point of having a high speed film cap at the tube is to supply immediate energy to the circuit when needed.

Grainger's suggestion is not different from mine - we just turned it into different words. Apologies if mine were unclear; it's been know to happen before ...
earwaxxer, thanks for the feedback. For teh record, do you have the CCS installed? Anyhow, I'll suggest you leave the cap in for a few weeks until you are thoroughly used to it, then remove it and see of you hear any change. Sometimes changes, like interconnects, have a preferred direction. (Sometimes not - I just want as much data as I can get!)
