Sorry, I don't believe her; I think she's misleading you. My wife used to say the same thing but I've managed to get an admission out of her that she does hear the difference.

I think she probably does hear the difference but doesn't care or thinks that the hobby is silly and that you should be happy with what you've got.

In this last bit, I'm dead sure that you're not alone.

You Sir are not alone and are in a group of similar situated husbands that is staggering in the number of its members.
I only am personally acquainted with one woman who has similar hearing to her audiophile husband. And they are supposed to hear better. My wife does notice the difference the Lightspeed makes, but she couldnt care less. Ipod all the way! LOL

She's right that this is an obsessively perfectionist exclusively male hobby, but she has no compassion for how darned addicted I am!

I have to secrete money and put it aside to secretly buy new projects - it's tragic fella's! Tell me I'm not alone!
You are not alone...

And I used to test all my new builds on my ex-wife. Women have better hearing than men and if you can find one that will co-operate they can be quite helpful.

Hi guys

I am trying to track down the source of a slight hum from my F5. My LDR attenuator in a separate case to my amplifier.

Would anyone happen to have a good grounding layout?

I had a quick scan through this thread yesterday but couldn't find anything

Thanks

Hi Richard,

I don't have an F5 earthing plan, but the following is an awesome guide to earthing chipamps and taught me about the importance of forcing the directional flow by using differently sized wires, and also how to eliminate earth loops:

Gainclone HUM, THUMP problems - The solution

It worked for me and I'm a doofus! Certainly worth taking a look at.

Hi Lucas

Thanks for the link

I'll double check my F5 tonight.

Guys-
I have some matched sets of LDRs, a board from Uriah, and an alps remote control set up on the Swap Meet section of this site. Sorry for the cross post, but I figured it would benefit someone if I posted here as well, as there are so many posts in that section.

Anyway, turns out I bought some other gear, which has a volume control, so I just don't need the items. Hopefully someone here can benefit.

Just search for my name. Thanks

Just received the Kit, and it's missing 1 Multiturn Potentiometer.

Can somebody point me the latest Schematic on this thread ?
the most update version ?

thanks
Cal

If one wanted to "preattenuate" before the LDR attenuator in order to reduce overall signal level to match a high gain amplifier and efficient speaker system, would it be best to use a two-resistor voltage divider before the series LDR, or just a single series resistor in line with the series LDR?

Any opinions?
