Wow, a suprise in cake box ??? I don't mind to get one for new year present We are waiting for your comment

Hi Huangyong, I want more of the single to dual, so please make it 2 for me. So my order: 2x SMD to DIP 2x Single to Dual Thanks! Bram Note : I will PM you my contact #

The price is confirm SGD 2.13 (w/ GST) for the 919639 (Dual 50k log). No stock for other values. I don't know how long Farnell will sell it with this price, so hurry !!!

The black resistors, are they the Welwyn 0.5%? Huangyong, have you got the kit and tried it?

Thanks Naz to move this thread! During discussion sometime out of track

Ok, I got the Farnell order number, it is : 919615 (Dual 10k log) 919627 (Dual 20k log) 919639 (Dual 50k log) 919640 (Dual 100k log) For your convenience .... The price list is SGD 7.08, but they charged me less than SGD 3.- per pot. You know sometime Farnell give discount for certain items without telling us Well I think it is odd to have centre detent for volume, so I prefer the one without. You are right about the bush, they a bit too long, so sometime we need to cut it (I use file to cut it).

FYI, I just bought small ALPS (around 1x1 cm body size) from Farnell, they cost less than SGD 3.- per piece. Forgot the order code. I will search the invoice if you interested. Snap in type to PCB, green color.

Sure, no problem. The neutrik cost SGD 9.-, and the fake one is from SLT B1-25 - Continental. Beside the outer ring size different, both Neutrik and the fake neutrik has a very similar construction.

Good idea huangyong! I'm not really tube fan, because of that, I would like to hear 'experienced' headphone listener to give some comment of how it sounds, probably compare to something else like PIMETA, PPA, or others, before I decide to try it Anyway it is good to see how many of us interested with tube amp, by starting another group buy for the MJ tube Cheers! Bram

Please share how it sounds Is the kit availabe for ordering ?

Great stuff Digi!!! Thanks! Don't mind show to us the mini tube board, schematic, and price please I think there are few of us that 'going tube' like what huangyong said

It works ! Now my Neutrik Locking Socket feels good, and the spring is not as hard as before. No more excessive force to use this gold plated socket. What I did: 1. Change the original spring with the spring I took from the SGD 2.5 'fake Neutrik' socket. 2. Give a little bit of petroleum jelly on the locking mechanism slot. 3. File the locking plastic latch a little bit, so it is now easier to unplug the jack.

I use Microsoft Visio

Thanks jtfoo! I think if you going to drive Op-Amps only, you don't need the +/- 48 volts, and you can change the transformer with the dual 18V - 500mA. Gillmore... yeah... very tempting... probably later after the PPA, or Gillmore first before PPA, ..... confuse Ok, I will finish my PIMETA first, that's my short term goal So when are you going to finish your pre amp ?

He.. He.. sorry to ask, but I'm too lazy to browse headwize. Don't mind to give us the shortcut for the power supply? Why you use META2 for the Jung multiloop? Why not the PPA one? Thanks!

Well you have a point, but I think I'm not going to bias it to much into class A, around 1 mA is good enough for me. Some people said, the difference is not really audible, so it is just a complimentary for me. And considering the voltage drop across the biasing circuit, it already take more than 1 volt. Means, the peak-to-peak output will be reduced by it. So for low voltage supply operation, to much biasing will limit the output voltage. Unless you are using transformer, you can have much higher voltage supply, so can have more biasing current.

I'm going to try the Neutrik locking socket, just got it from HungBros. I also have bought locking socket from SLT, which share similar construction with the Neutrik, but with manufacturing error, the right channel connector is too short for proper connection with the headphone jack (can be adjusted with plier though). But this 'fake neutrik' only cost SGD 2.50, and the spring is not as hard as the real Neutrik. What I will do is, I will modified the Neutrik socket, change the spring which is too hard, with the spring from the 'fake neutrik', and give a little bit of petroleum jelly for the locking mechanism for better pushing feel (no pron please ) I will post the result later.

What I tested are the 3rd gen and the newest gen (20 Gb, thin body, just bought), that belongs to my friends. I borrowed them for listening test, and IMHO, no significant improvement for the sound quality. It's about the same. My Panasonic PCDP SL-CT810, IMHO still sounds better with stronger bass. But don't take it too seriously, the different is just a tad, for my PCDP being sounded more dynamic with better bass. With lossless compression, iPod is still much better than any MP3 players out there. Tested with RS-1 and ATH-EW9

I still need the buffer, because the supply will be from battery, or adapter which only has + and - (no CT or centre tap). The regulator will maintain the ground voltage, but not function as ground, because the current that can flow through the ground pin of the regulators is very small. So, for current going to or from the ground, we will still need buffer to do it. Thanks for your comment!

The problem with MD is flexibility. They are close system to protect piracy. So personnaly, I won't buy MD. Another thing, the sound quality of 320 kbps MP3 is said to be better than ATRAC. So, go for iPod if it is within your budget, the reason is, they support lossles compresion which sounds very close to PCDP. Otherwise MP3 player HD base. But the iPod by default has no line out socket for the normal 3.5mm jack. You can get line out only when you buy the docking station About the sound of iPod, to my opinion, my PCDP (which is half the price of iPod) sounds better than iPod. I compare it with lossles compresion. It lacks of dynamic, and bass is not as strong as my PCDP (eq off). But it does sound better compare with 320 kbps MP3.

Hi guys, could you please advice me for the 6.35mm (1/4") panel socket? Initially I wanted to buy the Neutrik locking socket, but Mr. Fox said it needs some force to plug in and out the jack, so he use combi jack. I will check this combi jack later. Any other good socket? Thanks! Bram

Sure! We can meet up somewhere And one more Single->Double DIP. So total: 1x Single->Double DIP 2x SO8->DIP-8 (SMD->DIP) Thanks Huangyong!

Forgot the price, you can get both LM2941 and LM2991 from Farnell at around (forgot the exact price) SGD 3.5 and SGD 4.5 respectively.

Photos please

Wow... very well design and layout! Very neat indeed! I will order one if it's ready Thanks for the effort and all the cost for the experiment
