Hi Pheonix and Lumba,
Lumba -- 1000 bucks, cheap at half the price
Why did I build it ? Because it was such an unusual and original bit of thinking. I was interested I used to work a lot on repairing SMPS and electroylitic caps are the number one cause of trouble.
As to audio I prefer if possible not to use electroylitics, in fact my current amp has only two in the audio path. Rail decoupling is a different matter. Low ESR ( low tan theta ? ) and long life are everything.
I will be honest Lumba, I can't say I have ever sat down and done listening tests on individual components (capacitors/resistors) in specific locations in an audio component.
That subtleties exist in audio I am in no doubt and, it was dissatisfaction with amplifier designs I had encountered that led me to design and develop my Mosfet integrated amp. Quite why it is so good sonically I still can not fully explain. As you say, it is something that can not be measured.

Just ran across this thread, and as geocities is gone, all the links are dead.

I did find a series of 6 articles here:

DIYCore.com - Home

I'm still looking for the original, and possibly PWB masks.

hello all

I guess I am bringing this thread back from the dead I guess. I hope Mooly is still around.

reason I am posting is I have a set of pcbs for the Bateman tan theta meter that I bought from him back then. This was about 1999, i think. Then family and other stuff came along, and I never built it. I also lost the original information that came with it - parts lists, etc.

I did just find some scans online of EWW articles called "capacitor sound". But they seem to be a bit late (2002) and the boards are not the same.

I would like to see if I can get the right info for this thing and maybe build it - I am curious.

thanks if you can help me, anyone.

hmmm. It seems that what I have is a tan-delta meter, not tan-theta.

I am curious as to what that is, and looking for info still ...

I have his CDROM from back then. It has pdf's of the cap meter articles and I think some more info. Send me a PM with your real email address and I'll send them to you.

I just checked and I do have the Tan-delta article pdf's but no parts list or assembly info.
The text says he would have sent out a 24 page user manual and a 22 page assembly manual with the boards. Think you'd better search your loft again.
Still the article pdf's are a lot better than nothing, there's a lot of detail with part values and types given so it looks like you could work it all out.

Hi EssB, thank you!

Yes, there was a printed book with it, unfortunately long gone. I moved country twice in the meantime, amongst other things!

I'll send you a PM, thanks for your offer. Maybe I can figure it out.

Daniel
