And don't worry about "micro" soldering... I have designed & built a 1 Gramme radio-controled airplane ( 3 proportional channels= rudder, trotle, elevator), doing the soldering under magnification glasses...  

 

Here is the plane in my hand.

That's phenomenal! You should sell those, I can imagine kids (and adults) would have a blast with those little planes.

Well, besides those 1 grammes planes, I also built Helicopters or, more exotic, Micro-Jet planes with a 200 grammes Micro-turbines using Kerosene and running at... 230.000 RPM. Also with a smoke system for meetings : See this thread with building and videos in flight/take-off... 

 

and listen to the take off  :-))

 

 

 

 

 

Euh.... may be we are here slightly out of sujet ?? :rolleyes:

Oh wow, the micro one impressed me as do these! I love watching on youtube how far model RC aviation has come since i used to do it back in the 70's, fascinating. Do you fly full sized aircraft as well?

I got my private licence when I was young, but have not fly full size plans since 30 years, and honestly, considering the number of RC planes that I have crashed... it is better that I don't fly any more full size planes :o !

biggrin.gif Well, as you know, flying RC is much harder than the real thing! I am going through my PPL at the moment, have got to the stage of doing some solo's was up yesterday. my first experience with flying an aircraft was flying a Chipmunk when I was in the ATC. Always loved flying. So far my best memory was landing a Piper Super Cub on floats on Loch Lomond. Currently training in the 172.

Back again... finished reading through the entire thread to date... it was emotional :tongue: Personal favourite one and two (not a competition of course)

 

New question about TU-05 vs TUR-06. On the TU-O5 you can choose between different gain settings. On TUR-06 you cannot choose and it only says "8-200 ohm" output. So what can I derive from this? :redface:

above you see the new tube cleaning kit fast delivery service!

 

great, indeed. i always was fascinated by this micro jet engines. your plane looks gorgeous. what's about some tube rolling, sorry looping now?

 

if i want to integrate a micro remote control for volume and input for the tu-05 i now know whom to ask!

i assume you mean the impedance setting.

 

the tu-05 has an impedance switch as the tu-05 has output transformers so this is needed to set the impedance matching the impedance of the headphone.

 

the tu-06 is a hybrid design with i think mosfet's so no impedance switch needed.

so for me the abbreviation dummy , i learned what OCD is, but what is PPL, ATC?

Ahh, PPL= Private Pilots Licence.... ATC= Air Training Corp. ATC was for young people who thought about having a career in the Royal Airforce which I did!

there was a famous magazine in germany starting in the early 50's, the "HOBBY Das Magazin der Technik". i always loved to read the early ones, this magazine covered all topics around hobby, from building a tube radio, woodworking, cars, how do we live in 1975, military airplanes, the small cigarre box, television repair, the benefit of nuclear energy, how we live on mars:

 

 

Software: Microsoft Office

 

 

 

i think this thread has a lot of a magazine and this is one of the reasons i love it and love to post here. it is just the combination of (so called) on-topic posts, ideas, humor, heat robinson, airplanes, the munich tube rolling party (don't forget to participate), a bit of philosophy, design, from cables to modding, everything around you could think of, a lot to learn, nice to read, inspirational, lots of different opinions, nice participants, it keeps your mind open, free to think in any direction, always appreciated to have a new idea.

 

i always see my posts as a kind of article and spend hours on rereading articles, reformat them to look nice, correct typing errors or incorrect english language, change sentences to make them more clear, adding photos to illustrate something, so making them interesting and informative to read.

 

i love this mixture as i love the posts of bmichels having opened himself to show us some of his impressive abilities, making this thread even more interesting to read. i think everything here so far is on-topic as it is part of the great mixture that makes this thread a pleasure to read and to participate.

Thanks... I felt somehow embarased to be so far off topic.

Here here GG. I love the DIY aspect of this thread even though I am limited to isolation and pin cleaning but I am very much looking forward to when you get the larger case and go ahead with your project. Step by Step notation please! biggrin.gif
post #2070 of 3317

step one - open the housing

step two - do all mods (short summary)

step three - done

 

just kidding.

 

haven't received a feedback from shikada-san up to now if he is willing to offer me the second internal tube power supply pcb and if it is possible to get the also wider housing.

 

but spent a lot of time today in selecting components:

 

- +-0.1dB highend stereo potentiometer  (not  pure alps, a modified and exclusively for a german company manufactured one, about 120 euros):

 

 

the potentiometer above has the also main benefit of beeing smaller than the original one and space is the limiting factor for the modification.

 

input selector switch optimized for audio signals ( about 40 euros):

 

 

 

recableling - mundorf pure 97% silver and 3% gold wires (about 20 euros per meter), soundwise slightly on the brighter side, but very spacious, precise, great imaging and soundstage, less bass weight, great texture (if you believe what the reviews say) have to think of, but have the feeling that for the signal part i will go the silver way:

 

 

soldering - mundorf solder with  8.8% silver and 3% gold (about 100 euros 100 grams):

 

LEAD Technologies Inc. V1.01

 

selecting the components is very important i think because everything has to be passive, no relay input switch for example needing lots of current, so the passive input switch has to be of supreme quality. also the potentiometer is available with motor drive, but the remote control logic needs up to 200mA to drive the motor.

 

power supply - buffer capacitor (about 35 euros):

 


This is a great new capacitor design, as the capacitor has input AND output wires, so beeing always charged from one side and delivering the power on the other side, avoiding problems with mixing charging current and used current.

 

i will definetely extract the charger logic of two car chargers and then making a much more stable external power supply with two of this capacitors.

 

Shielding:

 

i already bought some mu metal (permalloy) to shield the different parts of the amp (about 20 euros):

 

Processed By eBay with ImageMagick, R1.1.1.M2a

 

the only problem with permalloy is that after bending it has lost its ability to shield magnetic fields and must be heated to 1200 degres celsius to get this ability again.

 

i also want to buy ready to use boxes to shield the output transformers, but did not look for a german source up to now:

 

LEAD Technologies Inc. V1.01


also there is the option to paint this parts with black color, so if there is not enough space in even the larger tu-05 housing, i will use such mu metal boxes to extend the housing and externally mount output transformers, neutrik jacks etc. .

 

as posted before, these are the vu meters (about 25 euros if bought in germany per piece):

 

 

this is the vu meters inferface logic (about 15 euros if bought in germany):

 

 

some connectors:

 

cinch (5 euros a pair):

 


loudspeakers (8 euros a pair):

 


additional switches, not finally selected, something like this (about 4 euros):

 

 

dac - hrt microstreamer 24bit 96kHz usb and usb powered dac with line out(about 180 euros, to compare size here with dragonfly usb dac):

 

 

P.S. btw, i now use one of my netbooks to post when at home, makes posting much easier than with my tablet.
