Dose it not get too stiff with heat shrinking?

However international post services still work great.

I want to build long 3.5 mm 4 pole connector cables. Cables go from PC, laptop, iphone to 10K input CMoy amp. Amp's input, output are 4 pole, for phone/mic headset, mic signal go direct from amps output to input, than through cable to device.   Anyone done this before? What kind of cable to...

Many thanks, tomb, this is exactly what I am looking for.

Anyone know links to good linear, preferably regulated PS in US ? Voltage will be between 12V - 30V   I built desktop CMoy for someone in US, need to help him with choice PS for amp. I have only European PS available.

Of course, amp building is great fun, and you can make amp in configuration best suited for your needs. I just misunderstand from your posts, you search someone who can built amp for you. Enjoy your amp building and happy New Year!

I have working O2 board without enclosure. I can make amp with mods for you, if you want. I have too many headphone amps anyway:)

Typo, I mean BF245 N channel fet, of course.   Actually I ordered NTE312 from Farnell and it work great in amp, so if anyone have parts problem, this is good and easy to get replacement part, only pins are different.   I buy some BF245A locally, not tested yet. Yes, and package with 2SK117...

Can BF254A work?   Or NTE312 maybe, datasheet:   http://www.nteinc.com/specs/300to399/pdf/nte312.pdf

Anyone know replacement part for 2sk117, preferably available in Farnell? I am waiting for package from Thailand, but it is too long time.   What parameters I need to look for similar working in CCS? Similar gate current (14mA) ? anything else?

I can recommend LM4562, sound much better than OPA2134. I don't like OPA2227 too

Today I receive screws and 5/64 hex keys.   At least in thees screws http://www.fastener-express.com/6-32-x-12-button-head-cap-screw-stainless-black-oxide-qty-100.aspx   5/64 and metric 2mm hex keys fit and work similar good.

Quote: Thanks for practical hints, I would not imagined, taping tool work not so well in thees holes. Now I need to find screws with length - original screws length + 3mm (my front panel thickness)   edit   Find it - 6-32 x 3/8 looks like perfect for my needs.

Welcome to forum, radjuga!   Of course I know those shops, perfect if you need to just screw something, bit harder if you care for look, better then average. And of course all screws only metric, no "american" screws. Anyway, I find screws in US, tapping tool in China and 5/64 hex key...

I have few boards at the moment.  PM  if you are interested.

Thanks MisterX, then I am going to order right tools.   I use 3mm tick front panels, are 3/8 screws long enough? After 3mm panel 6.3mm is left for Hammond's extruded canal. Is it enough for trusty long life using with regular battery changing, or better ordering 1/2 screws? What is your...

I am looking for nice button socket screws for Hammond 1455 aluminum enclosures. So far I use 3.5mm self tapping screws for metal. This works, but self tapping screws are usually with ugly heads. Hammond datasheet say #6 screws, so I find thees nice black 6-32 screws...

stupidmop and MonkeyD.Luffy, your boards are sent.   Zigis

Finally boards are ready. If someone are interested, I have 4 or 5 PCBs spare.

Google Gainclone

Thanks, stupidmop! At the moment I haven't any boards left, only 2 ready built amps. Few forum asked about boards too, so I think I am going to order next bunch. May be available in 2 weeks or so.   I ask about DT990, because someone wanted ordering amp for his phones.

Are anyone of Super-Simple 6DJ8 Headphone Amp builder or owner trying this amp with  Beyerdynamic DT 990 250 ?

Better change 10K to 1k-2K

Thanks, DudeMyCans!

My version of a Super-Simple 6DJ8 headphone Amp. Enclosure powder coated aluminum and oak side panels, linseed oil finishing.         This one is with lin out, parallel to headphone jack:       Inside - my own PCB, Alps RK27, PanasonicFM 1000uf power and output...
