Yes agree with edstrelow . I have had many breakages of my 007 MK1  all at the headphone clamping  position . To test I used an analog multimeter on the ohms range  using a fine needle I stuck it in ,inside the clamp and  another further down  the same cable conductor and metered both for...

Not someone who just plugs a part in and thats it  I noticed that my system was now a bit too open for me personally . This is not in any way -shape or form caused by the 2Qute  as it only reproduces  what it is given ,no my Stax SRM-727-mk 2 which I have heavily modified from sounding -well...

Just bought one 2 days ago  -my equipment - Cyrus xtse2+ pu -own built buffer using high quality audio chips - Stax 727 mk2 -heavily modified by me -Stax omega 2 mk 1 earspeakers . I found it to be very open and clear reproducing exactly whats on my cd,s great detail and contrary to some reports...

Johnjen I am very well aware of the series/parallel connections I have an AVO MK4  which I have used for decades before that a Taylor 45C I am referring to the  tube tester you are working on . If you dont believe me then check it out on the net.

Johngen it wont analyze  12 V tubes as it has only a 6.3 V supply. small double triodes that are dual heater/filament working are wired in parallel.

Very good advice Monte Verdi .

Soldering is just down to patience  the right size of soldering iron for the work you do and making sure the solder flows  over the correctly heated component with out creating a high resistance joint . Its a basic part of -do it yourself - that you should learn , if you cannot find a friend...

For some answers to your Mylar problem head to= www.2spi.com/category/polymer-films/  for a seller of it   also - www.gearslutz.com/board/geekslutz-forum/13668-mylar-source-html -surplus metallizing  chamber from an old electron microscope -vacuum gold depositing etc.  

You could try contact cement which is said to glue Mylar this comes in various varieties like a spray can etc it does involve a drying process.

I didnt bother replying to this post but as it is still on the go then in answer to it . Yes not through an "ideal " capacitor but tell me what electrolytic capacitor is ideal ?  You should know that electrolytic capacitors are far from ideal and show =RL-- leakage resistance while its starts...

 Hello again  okw3188 hope you got what I sent as there are 1000,s of pass transistor diagrams designing a truly individual one would involve many components and go against the principles of keeping it easy to build every person has their own level of electronic building expertise so this is so...

I have been reading about this DAC and like its design especially the discrete class A output . But I also noticed that several people commented on the earth the Chord 2Qute not having one and only a two pin mains connector that too I agree with as earth induced noise can cause problems . While...

Glad you are happy okw3188 I spent a year or more making modifications to see if they made a positive improvement to the sound quality rather than just a change of tonal quality. I believe the policy of Stax in removing the negative feedback in the 727  was in relation to a fad in the UK of the...

You,ve got it  okw3188 -third gold finger/spade in from each side ,same applies to the 717 . If you want the highest quality  remove the two SMD resistors and replace with a single 225K or high quality combination that totals it BUT they must be 500 V working this is very important if you can...

That would take me a bit of getting used to okw3188 but I like Australia for the quality of life there.
