Eh, no?

I'm guessing that his contribution to the redesign was probably on the order of how the product could be more easily constructed, cost ananlysis and how choices would be viewed by the buying public. I doubt it had much to do with the electrical intricacies of the circuit. I know I've offered that type of feedback for amb and tangent before and made meaningful contributions despite my rather meager knowledge of circuit design.

Craig and I discussed how to best implement the drivers in a small ~1cu-ft enclosure at CanJam so that's what I'm leaning towards. I hope that my dad I and will be able to build this some time this fall/winter, the drivers are getting lonely.

How do you mean? My stack? If so it should go like this: Headphone Rig (same as in current sig) Speaker Rig SB3/CD73 -> Hertsens -> SimpleSE -> Nugget Audio Cicada

Just started a thread about it in the DIY forum here.

It occurred to me a while back that my rig has gotten to a point that in terms of headphone amps it'll be pretty damn hard to beat what I have and that continuing to build more headphone amps is probably pretty silly. Where does that leave me? cue JBLoudG20 and Reks Speakers! Now I was talking with Pete the other day about basic speaker amp projects, specifically the design set forward in the boozhound labs howto pages. I had been looking at that project for a long time and had gathered about half the parts that I needed to complete the build but I was thinking of making some changes (different rectifier and input tubes) and solicited Pete's advice to make sure I didn't blow anything up. As an aside I asked him if there were any other, similar-in-scope projects and he mentioned the Tubelab Simple project as one. It clicked that someone here had thought about building it (fierce freak) but I told myself no, you've already got parts for one project, stay the path, ignore the pull, keep wallet intact. Yeah, this is how it always starts... So while browsing hoping to find some used decent iron for the boozhound amp I happened upon a guy selling an entire kit of parts for the SimpleSE. Turns out much like myself he had way too many irons in the fire and needed to bail on the Simple project to make way for others and he was taking a bath on the parts he had. Oh dear, I'm a sucker for a good deal. I fire off an email asking for more details and he responds back with the parts list that he has, which was in a word, pure insanity. Oh dear, I have a penchant for overkill. This puts me in full-on how the heck am I going to pay for this mode which results in the sale of my 'spare' stat rig and by 10:30 last night the parts were paid for. Christ, my wife is going to kill me. Much like the Menace I'll document as much of the build process as is feasible and will certainly share the results of the build. From all I've been able to read this is a fantastic amp. The version I'm building will be setup to run KT88s on the outputs and I'll be minimizing the options to keep it as simple (wink, wink) as possible. For now, all I've got is the schematic.

I'd buy the Rockhopper M

Link it up Beefy, I'm lazy!

Yeah, it'll be a nice companion, what with the stupid heavy and expensive iron that it uses. One of these days I'll learn my lesson and realize that asking Pete for advice on what would be fun to build eventually leads to my financial ruin.

It's hard for me personally to tell you how the M3 would compare to the kicas since I have no idea what it is. Got an internal shot you can share? Also, I'd hardly call the M3 mid-fi just because some folks on head-fi got it in their deluded little brains that because it can be built for ~$400 it only performs as well as similarly priced portable amps. Before the beta22 came out the M3 and PPA were just about the bees knees in terms of circuit design (ignoring the gilmore stuff for a moment) and still are if opamps are to be used as a part of the audio circuit. Also, what's your official company name so we can give you the appropriate title. I had no idea that you were a company or made anything. I'm a bit out of touch I guess.

Just a wee little speaker amp to go alongside the Menace.

My face currently looks like your avatar!

SimpleSE PCB Electraprint Transformers x3 Electraprint Choke Lots of caps and resistors Wonder what my wife will say when the box shows up at the house?

Well, when it comes to instructions there isn't much for the beta/sigma projects. There are parts lists and very loose assembly instructions followed by some initial setup procedures. None of which are terribly difficult but very unforgiving of mistakes. Also, simply stuffing the boards is maybe half the work, the case work and wiring is not insignificant.

I say this with all sincerity, the fact that you'd select a single rail PSU does not inspire hope that you'd successfully build a beta22. Don't be fooled by the PCB, it's a complex and involved build.

Don't worry too much about asshat sammich.

How about no.

2ch

Welcome Steve.

It's a single ended beta22 + a shite load of cables.

Hold on facepalm, didn't you used to captain lenovo?

Just 2. PM me if you'd like to discuss this more.

Hmmm, we might have to talk. I'm working on a 6v6 based amp project now...

I wonder if they'll actually have anything in stock this time. :|
