Here's an interesting device i put together recently. A customer who bough Patek had too much gain with the amp and asked me for an attenuator.

I made a simple adaptor, using Cardas hardware and nude Vishay, it came out really nice (and compact).

Hi Anand,

The kits, or mostly chip amps, have been going steady for last 4 years or so. I'm still surprised that even when I'm not updating my website I get constant flow of orders. This is probably one of the best diy products ever invented

It's also good that I'm not only concentrating on kits but completed amps as well. When one portion of the business is slower, the other makes up for it

Below test report on Premium amp (kit) published recently in Hi-fi news.

I didn't try any of those methods though, as I'm not using any active preamp and more amp gain was always desired.

I don't use an active pre either, but I have very efficient speakers and I've had trouble with too high gain earlier. I guess the best thing is to try both methods. After all, some resistors won't ruin me.

Yes, no problem. I can supply you with another set of screws.

Default my new gc

hi,
a little showoff of my new gainclone

Click the image to open in full size.

it's a premium kit with elna silmics and silver solder/ silver wires etc. with 2 inputs and one "rec out" - straight signal output without pot, also it will give the mute function to my amp in this position (i use the "rec out" with my headphone amp, then i dont need to connect the cables from sources directly to my headamp each time)

greets, ronald

Wow! Very sweet! Peter Daniel would be proud! Professionally done! I like your website as well. Love the understated look of the whole unit.

Best,
Anand.
