Default We Have Lift Off

Got the first one up and going on it's maiden voyage. Sitting here on top of it's little brothers. Robbed their setup to run a quick test. I'm always amazed when I flip that switch and get wonderful sound instead of puffs of smoke.....

This one does not have the manners of it's little brothers, it farts lightly on startup. I'm sure the family will be amused.

I measured 'em, they are 5mm.......
I went ahead and bought 5 of these blue Cree LEDs. Got some extras, they're cheap. Used one to replace the missing blue one from my kit, and used the three blue ones from the kit. The naked eye normally can't see the difference between the new one and the other three. But I can tell the difference, and when I take a picture at certain angles it really shows up as different. I should have just used 4 new ones, and that way I would have been assured they were all the same.

Not a big deal, just a note to be aware that all blue LEDs are not the same. If I get bored and ambitious one day I might switch them out so they are all the same.

These were comments on which wires to use where and a general assembly process. And of course the only reason I got that far was because of that really nice guide by 6L6. Thanks to you both. May want to consider incorporating posts #173 and #175 into the guide? Just a thought.
I was just bumming around the ACA thread to see if anybody needs help and along comes your thank you note!

Thanks!

I tell newbies and seasoned diy'ers all the time: "It's not about the destination, because for diy'ers there is none, it's about the journey."

I'm sure somebody famously intelligent and modest coined a similar phrase, like the Dalai Lama...so best to listen to those guys!

Best,
Anand.

Yes, but it's a musical fart.

Eating too many beans. Duh.














The “fart” is normal on startup, it’s the output capacitor charging.

So true, Mazeppa, so true.

I have noticed that my MF'ers (that's Musical Farters, of course) only do it in stereo mode. In bridged mode, they hold it, very quiet on start-up.

If you miss those cute little noises, parallel mono mode will bring them back.

I have a pair of low 86 dB efficiency 4 ohm speakers that are made up of a standard driver that crosses over to a BG quasi ribbon dipole panel at 200 or 250 hz. The panel takes the rest of the range. I've only ever driven these speakers with fairly high powered mono amps.

Yesterday I got the idea to drive the low frequency drivers with a stereo M2, and use the ACA 1.6 amps in parallel mono mode on the panels, as the ribbon is a non-reactive stable 4 ohm load.

I can't believe how good it sounds.
