Whatever happened to 41 Hz audio? The site seems to have just disappeared, despite having a quite admirable line of DIY amp kits. Is there another source for inexpensive Class-D power Amplifiers? Such a shame to lose this valuable provider.........
I am not surprised they have gone.
A quick search on ebay shows 18,000 listings for "amplifier module".
I had a quick go at selling them many years ago and it was a disaster.
I had to sell them at less than cost to move them on.

Probably a combination of too much competition and other things going on in Jans life. I think it was more or less a side project for him.
When 41Hz started he was offering one of a kind products; there were few alternatives for reasonably priced, good quality kits. Now the market is flooded with Class-D options.

How does anyone compete with a $11 100w/ch TDA7298 module that actually sounds decent (shipping included)?!
i could recommend hifimediy-amps, got nothing negative to say about them.
thats at least no everyday-ebay-seller 😀

A lot of cheap and good stuff to find that's for sure, but I'm not so quick to jump on cheap modules any more since I experienced extremely poor pcb's on some TDA7297 both modules and kits, on occasion I've had pcb traces evaporate during soldering, granted my skills are not the same as when I worked in a repair shop, but I still have no issue with tiny smd components and such. Also a lot of the connectors on many of the various modules have poor quality, so in many cases it's better to find modules without connectors.
Now I take my time before carefully choosing what to order, it's not that I've lost any great amount of money on poor quality. It's just very disappointing when you're expecting a half decent product and you end up using p2p wiring.
In my experience, 41hz and other "western" suppliers have had stricter quality control and more refined products overall, especially pcb traces have been better dimensioned, sad to see them go.

Jan's boards tended to use heavywieght copper on both the traces and ground planes.
Made soldering a difficult job without a decent soldering iron of sufficient wattage and even then it paid to pre warm the boards before assembly.
By comparison some of the Chinese (but not all) boards have traces that seem to evaporate at the slightest touch of heat.
But when a 41HZ Amp 3 costs around £30 in kit form and a complete Breeze TPA3116D2 in a case is just £22 shipped, what you going to do?
I'm sure that I read somewhere that Jan wasn't a well man and I wish him well and a speedy recovery because my dealings with him in the past were always excellent.
