So, my beta is on its way to be finished. I have a few ideas and not really any conclusion on what to do for vol control. I was thinking, Internal Alps Blue / Internal Chinese Stepper Or External (seperate box to be able to use with other preamps / headamps) Joshua tree or similar...

Just wondering how long it is taking people to complete this project. I have took three months to 3/4 stuff the boards and buy the enclosures! This includes the s22. No transformers or anything yet!

What is so special about them? Also does anyone know the series/model number.

Hi all, 3 channel beta 22 here. As part of the build the L & R channels are to be used as preamp outs, but my amps have no input caps, so naturally they should be on the preamp. Can anyone reccomend me what value film cap to use on the preamp outputs?

Hi everyone, i am thinking about using a JISBOS for the buffer stage in my preamp. Do you think it would be suitable for this application? This is how i plan to wire it all up, Input>>Alps50K>1ufFilmcaps>DRV134>>balancedout ......................................>JISBOS...

Instead of spending a good $70 on the 4 way connectors and their plugs, can i just use a 4 pole speakon socket such as this, Neutrik - Audio - Chassis Connectors - NL4MP-ST ? I dont see the problem if i only do the connecting when the power supply is off (to be used between s22 and b22)

Just whipped this up to power a DRV134, just want to check its all good before i go making pcbs. I intend to use 2 fixed 12v +/- regulators. I still have not decided on cap values properly.

I am looking for somthing like this I have looked around for a couple of days and i cannot find anything that isnt plastic. Any ideas?

I would be very happy if someone could order me 4 x DRV134PA and airmail them to me, i am willing to cover all costs and time. Thanks

I have finished a ck2III, currently building a starving student but because about 40% of my library consists of 1960's - 1980's reggae and ska, i feel like i need somthing to bring these recordings 'back to life', and not be so harsh on the ears with the highs, as quite a lot of it is bad...

Can someone please tell me what i should ask for to buy this kind of screw? I have looked and i cannot seem to find it. Attachment 8747

Here they are, for the hammond 1455t2202 enclosure, the actual front panel is inspired by a fellow headfi member as you can see . This is the first time i have used schaeffer ag so i hope they turn out ok! I have double checked all the dimensions. Sorry for everyone with smaller...

Capacitor is 2200uf, as i have one laying around. I have whipped up a quick 5 min design for a 12v regulator to power leds's relays etc. A 12v 5va transformer would be connected to the ac inputs. I know i have not labeled the schematic properly, but this is just a quick thought. Does...

I am looking to build a dac, that i can get in kit form. I need somthing that can take usb and maybe s/pidif coax. (no optical). This is to be my main dac so i dont think the alien dac would be good enough. I plan to power this from a s11 psu. Anyone have any suitable suggestions. Last of all...

Well, i am thinking about building a bijou, and i was thinking do i actually need to ship the transformer over from america? I have seen this on the cavalli web pages. Does this mean i can wire the mains (241v as of today) with a slow blow fuse directly to the power supply pcb, then use a single...

Hi all, it is now time for me to find some hookup wire for my amp project. I am looking for somthing between 22-24 awg but i cant seem to find anything under 30.5 m which is far too much to say i would need to buy red and black to keep things clean. Does anyone know of anywhere which i could buy...
