New-building of my F5

[steenoe]

Dang, no wonder my holes are all crooked.

If you have a place to set it up, you really ought to get yourself a drill-press. I have a cheapo one that has drilled a few thousend holes and holds a 0,8mm drill-bit. It is the single best investment you can do, if you have a place for it! Price here in DK approx 120$

drill press

Steenoe - even better.
It's funny the tools I've never even considered.

Something to add to the basement collection.

You will think of me with love, first time you drill a heatsink in one of those While shopping anyways, you also need this, to hold your pieces (smaller ones):

Tools

Yes, I will think of you with love, for many reasons!

Yes, a small vice is a great addition to the bench. A variable temp soldering iron is my favorite. However, occasionally I forget to take it off de-soldering 900 degrees.

I also consider adequate lighting for me to be very important.
My next investment is a shop-vac. My other just died.
Probably too much aluminum shavings and soot from stove.

Heck, I dont even know the other reasons

So far so good . . . well progressing.

Probably, I could try listening the day after tomorrow. Haha . . . but, I have to stop here for four or five days. I should prepare myself to have a trip to the the hospital in Seoul. Three hours by bullet train and half an hour by taxi. Three or four days of chemo . . . >><<


Cheers,

Hi,
Nice set-up! I've also started my F5 project and I'll follow some of your construction tips.

By the way, I've seen the first photo of this post, and I belive that you will get much better sound if instead of investing in a new amplifier, you build a nice pair of rock-solid stads for your monitors. Mine where built with solid marble and the sound improvement was impressive.

Bye!

One week . . . I have been in darkness. I have been not able to access diyAh . . . for one week!

Thanks to Mark (Variac) in Papa's country and Jim in Downunder, I finally see no more of the error code HTTP403. Instead, I read diyAh . . . & friends.

I have wanted to show my F5, which has been completed last week.

Cheers,




Last week, I have met my doctor in Seoul. But, he has returned me back home in Pusan, saying that number of my white blood cells is too low for the chemo. That's why I am in Seoul this week. And, that's why I could have completed my F5 last week.

After the adjustment of bias and DC offset, I have measured voltages within the power supply unit as attached.

Huh . . . ? Only +/-28V before the regulation . . .

 

[Babowana]

Mmm . . . only +/-28V . . . If so . . .

What about this?

The PSU is now ended up as shown here.

It is just beautiful.

You have got a pair of huge heatsinks - nice! How expensive are they in Korea?

Thanks, friends!

Before any talk about sound . . .

Let's take inside view. There are too many wires even though I'm using PCBs. This means that my plan about the building was less brain-work. Hahaha . . .
