Unfortunately the paintjob is slowly chipping away on the edges...

on my hand for the past 3 weeks. It (the cast) finally was removed today. So I was itching to go.

Here is the result:

First spider done.

The Takman resistors have thick copper wires. This makes for wonderfully strong little spiders.

I've also used ceramic terminals strips for the first time and it makes for a nice strong construction.

And I did the ccs for the phase splitter a while ago.

[edit] I used silver solder. But found out that it is NOT necessary with these fakes. Fake or not it make for a great construction.

"TEKTRONIX CERAMIC STRIPS, HISTORY and GENERAL INFORMATION
Tektronix first developed and used ceramic strips in their oscilloscopes in 1952. During the manufacturing process, silver in liquid form is painted in and on the notches of the strips prior to the application of the final glaze and final firing. The silver is then firmly bonded to the ceramic and wires can be soldered directly to the ceramic.

Special silver-bearing solder should be used when soldering to ceramic strips so the silver bonded to the strip does not...

A few pcb's more...

Posted 7th December 2009 at 09:40 PM by Bas Horneman (Bas Horneman's diyAudio.com blog)
Updated 7th December 2009 at 09:58 PM by Bas Horneman

With a dayjob and other "stuff" in my life. I don't always feel like conquering the cold and messy shed to go do some drilling. But I usually have other projects running parallel that I can do something on. Pictured here is the Pass B1 and the lightspeed pcb's. Stuffed...primarily because..... that way I won't loose parts in my messy hobby room.
Click the image to open in full size.

The Kendeill caps were too big for the B1 board. So I soldered the neg terminal to the neg hole in the pcb and wired the plus to the positive rail.

The wires of the 10uF cap I bent to go beneath the pcb and almost touch. I did this on purpose because I have some 0,22uF smd caps that will act as bypass for the Audyn polyprops. They will go between them wires there.

A few holes more...

Posted 1st December 2009 at 10:28 PM by Bas Horneman (Bas Horneman's diyAudio.com blog)

It's funny but one does not realize how much time goes into a project like this. In my case anyway.
Taking the time to find the correct spacing etc.
And after you've drilled the hole you realize that it is just not big enough. Out comes the metal file and you have to use some elbow grease to enlarge it just enough so it will fit. Then you can't find the other cap. Thus the decision is made to pull the ASC's from an old project. Etc. Etc. And all I have to show for this is one little picture.

starting to look like it...

Actually wanted to continue on the Baby Huey but it was late. And did not want to keep everyone awake while drilling.

Some more parts arrived for the BH

specifically I wanted to show the deflex washers that I'm planning on using.

Click the image to open in full size.

The deflex washers will probably look ugly. But I'm planning on putting them on top of the aluminium top plate. And having a bolt with separate brass washer "hang" on them. This bolt will then pass through a larger hole in the alu chassis plate to the wooden sub chassis that houses the tubes.

Also got the 470uF/100V caps for the bias blocks.

It'll take a while to build the gainclone ;). And I'm going

to need an attenuator as well. Because the Gainclone will be set up as a power amplifier only. I put together a makeshift attenuator of parts I have. And of parts I want to use in a full blown tube preamp.

That way I can ...dare I say it...burn-in the transformer. Even if burn-in does not exist...it won't hurt.

Also some mock up shots of the GC. "Enclosure" is some Ikea DVD storage system that was on a sale. Something like 2 euro's or so.
