I am wondering and trying to find the shaft size for the quickie knobs to source different looking knobs for the quickie I bought last week and waiting on its arrival.
-
It's 1/4".
-
Thank you but most vendors are listing them in millimeters which is what I am looking for if possible
-
1/4" = 6.35mm
-
tym
-
now i see why what comes with the kit, nothing else avaialable on the bay.....
-
Try some electronics suppliers like Mouser and DigiKey. 1/4" is a very common shaft size.
-
ok i will ty
-
Radio shack has them - cheap
-
I ll check the shack thanks
-
OK update on upgraded parts.
I have not recieved the quickie but here is the upgrades I have purchased so far.
PCJJ upgrade card with quickie
Vintage NOS Noble Dual 100K Potentiometer- Alps Blue Beauty replacement
Pair N-Cap Neglex MKP 2.2uF 800V Capacitor HIFI Audiophile Grade Germany
2X ROE ROEDERSTEIN 2.2uf 63v Axial Capacitor FOR AUDIO
2x NOS US Navi JAN CKR 3S4 VT-174 DL92 Battery Radio tube
2pcs KENDEIL 100V 1000UF CAPACITOR AUDIO
Anti-vibration Pads/Isoblocks for Audiophile Equip. 2"X2"X7/8" (set of four)
1 Quart QT GT Liqui-Damp X Brush On Liquid Audio Sound Dampening
I have top line rca jacks
Batteries from radio shack industrial grade.
I hope this works out

My suggesting - worth all you are paying for it - is to build it bone stock first. Listen to it for a number of hours - the caps or whatever do seem to need time to break in - THEN do the upgrades.
I tried both the chokes and PCJJ and the PCJJ was a BIG up over stock and even the choke mod.
-
I have been reading and I thought you either use the pcjj or the chokes, are you saying to add both to it one at time or either or?
-
Dawg, we say it that way in Georgia, before you swap out the caps you can break them in:

thank you for the break in link , sometimes I use them as power supply temp bypass filter caps,or I use capacitor tester to break em in.
-

One or the other. You can use chokes or PJCC mod, not both at once.
They both increase the gain but the PJCC sounded "smoother" to me.
Your Milage May Vary
-
ok thanks ill stay with the pcjj then
-
Ok, maybe I'm just lazy, but I don't remember seeing a price for the chokes. Would be a simpler install, not that pjjs is a problem.
-
pjccs sooooory

Thread on the chokes here:

You source the Hammond chokes from an outside supplier. Not expensive.
As I said I find the PJCCS better but others prefer the plate chokes. Worth a try.

Here's the choke link

Batteries from radio shack industrial grade.
Now there is an oxymoron if I have ever seen one!! ;)
Quickies are fun and perform to an amazing level! Radio Shack...not so much! ;D

I was just trying to find reasonable batteries is all, and at least the shack changes the stock frequently. :D
-
FYI - a 47uF-100uF at 6+V will work for the cathode bypass capacitors.
-
why such a high value capacitor, normally I bypass power supply caps with .1 to 1 uf caps?
-
A bypass capacitor implies that it's bypassing a larger capacitor.
The capacitor across the cathode resistor is there to act as a short for AC on the filament, removing degenerative feedback that would otherwise be there.
The cathode bypass cap also stabilizes the bias point, though this becomes unnecessary with the PJCSS upgrade IMO.
The size of the cathode bypass cap must be sufficient to offer the same "short" across all audio frequencies and then some. The 1000uF cap we put in the last Quickie was used because we already had it, the new Quickie uses a 150uF capacitor that we added to our inventory for the BeePre.

The above post is an example of Bottlehead's business acumen. Stocking a new part costs money. Until it is necessary you don't do it.
-
so based on 1000 uf and 150 uf, I assume since I just ordered one its coming with 150 uf caps, so I have some nice mundorf 390 electrolytics that should work ok?

The caps I have are bipolar 390ufd 63 volt, but I am not sure what side is the negative either, I feel stupid being in electronics 25 years and cant tell, tried to google but mundorfs site couldnt tell me.Anyone know if they will work and which side is the negative?
-
You mean there is no stripe on the Mundorf?
-
Bipolar electrolytics are just that - no polarity, either end can be negative. They do have a reputation of sounding better than polarized electrolytics.
-
A 390uF/63V cap will work well, and the new layout has more room for such adventures.
A bipolar cap doesn't technically have a positive and negative side, just hook them up as you like (but be consistent if there happens to be two different lead lengths).

Thank you paul and cauc I rememebered finally, hence then name , bi, both ways. I did find nos nobles volume controls and they are stereo but each side has 4 posts instead of 3. Any idea's?
-

on these no there isnt, but we figured it out.the leads are the same size also. but since these are bi polar, bi, both ways.

I think a pot with 4 posts may have a tap for loudness, you'll probably have to use some clip leads and test it out and see how it should be hooked up.

ok when it comes in ill meesage you with measurements
