Hey everyone!
Hoping someone can shed some light on this amp.
I’ve seen specs for 4 and 8 ohm loads but what is it for 16ohm?
Running a Pair of TAD TD4002 drivers which are 16ohm nominal.
I know I only need a few watts but just curious to see what output is.
Thanks!
Good luck to everyone who entered and thanks to Jason and Nelson for making this lottery possible!

If need more power You can try 16 Ohm big power resistor connected in parallel to TAD drivers
so the amp will see 8 Ohm load, it's classic Papa trick

Hey, quit trying to steal my kissing up!
But 100% agree. Love the fact the man and company that sells 4 and 5 digit amps gives us the ACA for under $400 shipped. Been using the ACA as my computer audio amp and it's perfect. No noise, none, and just sounds good.

I would use the 8 ohm amplifier spec and assume the power is 50% less. Then after that guess try actually measuring the ac current fed to the driver. Use a full wave bridge rectifier and measure the dc current when you play the driver using a tome generator. (fixed level tone) Just a humble guess.

Round 2 winners announced
The winners for round 2 have now been drawn. Congratulations to the members below.
For everyone else - thank you for participating. This was always going to be tough, with just 1 amp available for every 12 members who wanted one. Nonetheless I hope that this this exercise was a fun and entertaining (if no doubt nerve wracking) diversion from everyday life during this difficult year for you.
A reminder that this very limited supply of amplifier kits have been produced not-for-profit as a way to say thank you to everyone for their contributions over the years. There was never going to be enough for everyone to build one, but everyone was able to at least participate in the lottery.
If you missed out on getting this one - don't worry, there's more coming in the future. You'll just need a little patience. If you entered this lottery you will be given priority for those future offerings.
Any profits generated from this exercise have been and will be donated directly to the nominated registered charities. People purchasing the kits can choose to "tip" at checkout (many did) and we have donated 100% of the tip on their behalf. Many members have also made independent donations to these good causes.
If anyone else feels inclined to make a donation, please use the links on the following page so your donation can be counted towards our goal.
Donations to two great charities
So far we have raised $1,999 for the American Foundation for Suicide Prevention and $2,137 for the Prostate Cancer Foundation.

STATS DEBRIEF
==========
As with the last round, the drawing was performed at random, according to the rules, and without fear or favor.
NOTE: INTERNATIONAL SHIPPING FOR ROUND 2 IS DHL EXPRESS ONLY
=============================================
This round, we are requiring that all international shipments of VFETs ship with DHL Express.
Last time we drew 88 of 90 allowing 2 for shipping mistakes. We lost 4 due to problems with lower reliability services. Shipping during COVID is still fraught with problems. While the store guarantees you'll (eventually) get what you pay for no matter what service you choose, these VFETs can't be easily replaced. Nelson has graciously offered to replace the two we didn't have replacements for, from round 1.
We added DHL Express to the store's shipping options this month, spurred by the EU's July 1st changes in tax collection laws. This service is "delivered duties paid" which means no "box opening fees", no customs delays and no more to pay. DHL Express is a premium shipping service, both fast and reliable, and we have negotiated a deep discount on their rates for you. All VFET shipments are required to ship with DHL Express.

Thank you again to every diyAudio member for participating, their good will, and generous donations. I'm very proud of this community.
As for the future - we're always listening and learning, and will strive to improve every aspect of how we do things in the future. Right now a lot of ground work is being laid for better things in the months ahead. I hope you'll enjoy the improvements to the site, forum, and product offerings that are planned for later this year.

Congratulations to all the winners. If any of you find yourselves too busy, or flush with the success of being drawn out of the barrel, now disinterested in the prize, I put both hands up in your place...
Best of luck with the construction and may they offer many years of listening pleasure.

Sigh, I guess it wasn't meant to be, as I'm listening to my lovely AJ. And, to be sure, another project would have added to some complications on the domestic front ;-) But congratulations to the winners- it sure is a beaut; and even bigger congratulations to the organizers who put this all together and executed it flawlessly. I never cease to be amazed at this community, the millions of person-hours it represents in help, advice, counsel and just plain ol' enthusiasm.
