Well if one of you fine gentlemen would point me in the direction of a not to difficult project with about 20 watts stereo to power what i hope to be the worlds best speakers 😀 i would greatly appreciate it.

My tube amp projects are usually less than 10 W, and based on recycled iron -- ie design follows what has been salvaged. EL84 SE & PP, 6BM8, ECL86, a few EL34 SE & PP.

There are a number of Pass inspired amps that hit 20 W... the miniA that is goinf on right now is one...Nelson's ZEN 4 (boards & semis available from PassDIY)... the simplest project -- good to get your feet wet, is a gainClone. semi Kits can be had from BrianGT, Peter Daniel, a number of others. I'm looking forward to the Tube Buffered Inverted Gain Clone (TBIGC) that Franz & Digi are working on, and the XGC that Nelson inspired & is almost to the boards available stage.

I purchased 8 x 8 inch drivers last week. Now after some of the line array and open baffle information started to become coherent in my head, i realized they were useless to me. So i paused the order, not cancel now i have it in my head to go with 12 6.5 inchers.

I dont know :xeye: i want big open sound thats not nessicarily loud, just BIG. I have a lot of concert and club time from my old days. I dont like small sound (again i am not speaking about the SPL ) I did some beautiful wonderous things in Car Audio but its a car, so it was never big till the DSP's started to become popular. The only car that ever topped our stuff was a BMW where someone took B&W 801's apart and installed them as a front end. That was BIG sound. And Holly Mongles' Ferrari. Anyway i am wandering. I am all over the web right now drinking wine looking for any kind of a design that would be big enough for Led Zeppelins Houses of the Holy.

Dr.Jims Needles, as cool and impressive as they look, i just cant see BIG sound out of an array of 3 or 4 inchers. And according to my math off that white paper, 8 is to big. SO 6.5 is a compromise.

OR

I go the SL open baffle route using the line array technique. If i do that i definetly have to get those 250 dollar / ribbon tweets out of my head and buy something cheaper for a parallel array.

I also want to build some tube amps. Too many things to do and not enough money. SO speakers first and ill live with the equip i have available.

So you are in a situation where you have a credit with a vendor and aren't yet sure how to redeem it?

An open baffle can certainly produe big open sound -- and usually with little effort. My $7 Open Baffles are a clear indication of how much of an advantage an OB can give.

Can we ask what vendor? You seem to be stuck in Danish-land as far as drivers go... for an open-baffle i'd be looking elsewhere.

Looking at some of those projects, will 20 watts be enough ? And now the price factor comes in. I would need 4 of those mono blocks. It might make sense to get a member here who is not more then a few hours away to build them for me and pay for it. I can see that i would have to build 3 or 4 kits just to "get it' before i tried a 20 watter.

Blow up my apartment :dead:

That's the opposite of my experience, Mike. Part of the beauty of the Aleph series is that they are fairly simple circuits, hard to mess up if you take your time and are meticulous about checking component values and connections as you assemble your amp. Of course, your first testing with a speaker shouldn't be your new line arrays.

I took my time stuffing the boards and my first three Leach channels worked fine right off the bat when I hooked up the output stage. For the fourth, I guess I got overconfident and switched my color coded wires to the output stage and the PNPs were connected the positive rail, NPNs to negative - thank's to Prof. leach's recommended testing procedure I didn't blow anything. I wasn't so fortunate with my first A75, and the failure was due to a board stuffing error. I'm glad I bought lots of extra output mosfets. I've dialed back the pace of assembly and increased my QA inspection, so my breadbooard mini-As worked fine first time out.

Just go for it - there's not much more satisfying than beautiful sound out of a system that you largely built yourself. 😀

I am dealing with Solen.

WHo makes better drivers then the Danes ? Are you Austin's fawshaa ? They blew up your kids ? 😀

Well if you want highly articulate but boring speakers with not a whole lot of dynamics... perhaps.

I know Solen well (i'm a dealer). For open baffle build it around a single Visaton B200 per side. Add a tweeter -- i'll have to look to see if anything other than LCY, and a couple BIG bass drivers on the bottom (actually i was very happy with the B200s by themselves and one could certainly start there and grow the system)

Dude ranchette
Pygmy Ponies
Zircon
Frugalphile
Austin's fawshaa

What are all of these :scratch:

Mostly humor - Ar Ar. (Mork and Mindy refeerence - dating myself)

Dude Ranch is a farm for entertaining city folk - the suffix ette makes it a small one. NP has mentioned that he keeps a variety of animals on his property. In California only the fabulously wealthy can afford much land, so he has a ranchette.

Pygmy ponies - small ranch -> small ponies, I took as a reference to a Frank Zappa song, Moving to Montana, wherein Frank sings about his dream of making a killing growing dental floss on a ranch in Montana.

Zircon - another reference to same song, makes the tweezers shiny like fake diamonds

Frugalphile - someone on a quest for great sound, CHEAP.

Austin's Fawshaa - Not sure, but I guess a reference to an Austin Powers movie

Funny how we forget sometimes that pop culture is not quite universal.

Now go out and listen to as much Frank Zappa music as you can lay your hands on. It's wonderful stuff, even more amazing when you consider his dream was to be a classical composer. 😎 😎

Zappa was the 2nd LP I ever bought, after the Beatles
White Album. At this time I now have as complete a collection
as seems to be possible, vinyl too.

Were you late into the game Nelson... i always imagined myself as younger than you but i had quite a few albums before the White album was even released...

My Zappa collection started falling off when it started to be NA on vinyl -- i have a milk crate just full of Zappa vinyl. It is nice to Barko Swill continuing to bring the archives to the light of day. Got the Baby Snakes DVD for Christmas... enuff teasres in there to hope for the entire Billy the Mountain saga on DVD.
