Kalimba - New clip demoing both Ojai and Tag circuit

[Max]

I'm not sure what you referring to Scotty

Hi, Mac Daddy,

I am at least rather sure:

Scott posted a clip done with his Glaswerks Phat Momma EL34 in his opening post, that is a clone of #183. Tag posted that in his ears the Phat Momma doesn't sound like #183 in this clip.
Now you've posted some clips of #183 lately here in different threads. Now Scott posted, that one or even some of these "#183 clips" you have posted, has/ve not been recorded with #183, but with his Phat Momma.

Now Scott argued in Tag's direction that obviously Phat Momma sounded at least close enough to #183 on this/ese clip/s to fool you and everybody else here (everybody else: no one stepped out and posted: "Mac Daddy, this clip does not sound like #183, you've mixed something up!").

Now the "tone quiz" is: Which clip/s of all those you've posted lately as being a clip of #183 is/are (a) clip/s of the Glaswerks. As TKT, at least he will easily find out and report. So IMO there is no need at all that Scott spoils the tone quiz by just telling us. So perhaps let's just wait and see who solves the riddle. Or are you in any hurry concerning this?

All the best,

Max

Hey Max
I'm not sure that is the case
I have a bunch of clips that Scott made of this Amps & 183 That were done before he Cloned that Amp
I posted some of the ones that were 183 on different threads
At one point I just quickly made copy's w/o re listening to them when I posted them , So its very likely thats what happen

With that said , I've heard this Clone clip , I like it , But I don't hear anything that sounds remotely like 183 coming from it
The true proof is hearing them in a live environment , Side by side
Playing them thru what ever Cab , Speakers , Cable's , Guitar Etc, Sounds best for that particular Amp

Hey Max
I'm not sure that is the case

I am, because I think that the content of Scott's post is rather clear concerning this:

Obviously you've posted one ore even more clips that Scott recorded with "Phat Momma", a clone of #183, as being (a) clip/s recorded with the original #183.

So if I did not misunderstand Scott, the difference between the clone and the original is obviously not as obvious as you write:

But I don't hear anything that sounds remotely like 183 coming from it

Or, if it is that obvious for you as you write - wich one then is/are the "Phat Momma clip/s" of all those you've posted as being "#183 clips"?

Cheers and all the best,

Max

Jelle did you remove the tube and ground the cathode end?

...maybe you need a real cheap ass meter instead of a fancy one?



Mr. Thevenin can eat it too guys cause I get repeatable results in this example as well as in measuring caps under the goop.....which someone here once said could not be done without several thousands of dollars of test gear...

Whatever!

In any event guys this works... it does... Look if the cap says 250k and it measures 29pf then what does that say to you....that is is really a 250pf cap?

Because I can drop a 250 in there and it is not going to read anywhere near 29pf... So now what?

I dunno folks....not sure I understand the reasoning that would suggest I am wrong when all that others can suggest is that "maybe is it really a 250pf cap" and so and so says "Not huh"

Come on folks... Answer this.... the cap says 250K, your trusty meter says 29pf... what's YOUR best guess?

250pf? Really?

[ampdork]

Also in regards to the actual code wqritten on the cap please check this link, type in the code 250 with a tolerance code of K and viola what does it say?

If I am being obtuse it is because I am correct and kind of bothered that anyone would suggest I would lie or could not obtain the facts without some degree.

Shad,

Nothing personal was meant from my end. I just ask questions...I'm a scientist, you see?

I'm not questioning the cap value in 183. I'm asking, yes asking, why I cannot duplicate this result. Please understand where I'm coming from, I'm a scientist and measurements need to be reproducible by others in order to be generally accepted. I do understand this is not the peer reviewed scientific community here, however I am trying to learn from this.

I removed the tube and did not desolder anything. I'm assuming you did not either in 183. I do agree that it's possible to read a number of cap values under the goo. But for these snubber caps I have always found the need to desolder if I wanted to verify. But I did not ground the cathode end. Thanks for the clarification.

As for the 250K thing: I have a couple of thousand ceramic caps that have 250K written on them that read in the 250pF range. Shad, please do not take my questions as personal attacks. They are not. Just questions.

Again thanks for the clarifications, very much appreciated.

Jelle my response was not meant to be directed entirely to you.
My apologies for being gruff.
yes i too have caps with 250 written on them that are 250of, but I also have 250K that are 25pf and it is a commonly excepted code.
I understand your view but am just trying to support my own findings until such time as someone can verify the results in their own experiments.
So please accept my apologies as my post was more in general...only the bit about the method really was meant for you directly. Please try it and report what you find.
Again not at all trying to be dickish guys but I have done this several times on many amps, real Dumbles and clones and have always gotten very accurate results...
Please do try the experiment again. I am curious to know your findings.

Scott as I posted earlier
It was done in haste , It was my mistake that it was posted w/o listening to it before doing so
You can put you own spin on it if you please
But the clips speak for them selfs

Apples & Oranges.. I believe you would say

What we talk about in person or on the phone , Seems to lose some translation when it comes to being posted on the internet
But please don't give up

I will always respect you , You are a gifted soul searching for the ultimate tone

http://www.electronics2000.co.uk/calc/c ... ulator.php

"Value Codes:
The capacitance value is often marked using a 3 digit code. This works in the same way as resistor coding but using numbers instead of colours. The first 2 numbers give the value and the last number is the multiplier. These give the value in Picofarads (pF), e.g. code 103 = 1 0 000pF (=0.01uF - see Capacitance Conversion Table). Alternatively the value may be marked directly, for example 2n2 is 2.2 Nanofarads (nF)."

Max the codes are correct for a 25pf cap and my meter tested said caps at 29pf.

Given that this is all the info you have available are you suggesting the evidence leads to it being a 25pf or a 250pf cap?

Hi ampdork,

up to now I don't see any "evidence" at all, neither for 25pF nor for 250pF:

http://en.wikipedia.org/wiki/Scientific_evidence

And my post you referred to was meant as an informative comment and not as any suggestion at all.

But if someone would ask me concerning a suggestion of my own, I would - for cultural and financial reasons - perhaps recommend not to remove the pickup covers from a still all original and previously untouched '59 Les Paul Custom in at least excellent condition in order to find out the colour of the bobbins - or for whatever reason.

And if someone would be in doubt concerning this, I would perhaps further recommend to ask Walter Carter or George Gruhn: http://www.gruhn.com/
AFAIK both are very friendly and knowledgeable guys concerning the question: "How to treat collectible instruments?"

All the best and a nice weekend,

Max

I would take those suckers right off and have a good close look.

Max, That's funny!
Seems like the more I read about and hear tone comparisons the more I believe the mind is hearing more than the ears! By the way, TKT.
