Thanks Andrew for the tip. I have started looking for heat sinks to fit those 8 pin dips, but all that I have found require huge orders. You wouldn't know of a distributor that would do perhaps 25 pieces.

Try Ebay, you will find these types of items fairly cheap there.

Hi everyone,

I have attached some pictures of my build. Any comments welcome!

Muskyhuntr, thanks for your initial impressions, I will be interested to hear of any changes you make along the way from standard.

Currently mine is as per build spec, so far my initial impression is of an extended frequency response, sounds a little laid back at present , but the set up is only temporary, just to test. I am using a VPI TNT HW19 mk3 turntable and Tag McLaren power amps into Kef Reference speakers. The output is very quiet despite the huge amount of gain.

Cheers

Bigtone

Hi All,

Bigtone mentioned in his review that this pre-amp has a tremendous amount of gain. I concur, and should have mentioned it in my brief review. Like a kid, I had to see how fast it would go and gave it a brief rev. I was very surprised at what came out. Not recommended!

Andrew, thanks for the link. Will be ordering some soon.

Jim

Great looking build there so far Bigtone. I'm in the process too. See my thread here. I have a little better idea now just how many cables we're talking about for this bad boy!

Hi All,

Received my rear panel a couple of days ago. It turned out pretty good, but not perfect. A few pictures are posted below.

Still have to add some shielding around power supply and add a few spacers to the in/out boards.

I have posted the files for both the front and rear panel and an Excel file detailing the cost of this build on the Elektor web site. (for some reason, I can't do it here). Note that on the rear panel, spacings will have to be tweeked for each build due to variability on inserting parts into the in/out printed circuit boards.

Looks pretty good from here

(have you tried putting the files in a zipped folder if the forum won't accept a particular file extension)

Hi,

As per Mooly's suggestion, I have put the panel files into a zipped folders. This seems to have worked as the files were successfully uploaded.

Default Advice on adding Self Tone Controls to Pass B1

Hi,
Sorry not to be a purist but given the range of material that we play I have come to the conclusion that some tone "tweaking" is needed.
I already have a Pass B1 buffer feeding my Aleph power amp. I am planning to simply insert the Self tone control board between these two.
This may sound naive but so far I cannot see any problems.. except perhaps that the P1 is now superfluous.

Can anyone advise / comment on this plan .. but avoid arguing about tone controls please?

Thanks for the help

George
