SURFING MUSIC SOUND-WAVES

Thank you for visiting.
I want to share my course seeking audio nirvana with you. I am not a EE  by profession or education,  I don't claim to be a technical expert and I don't have unlimited funds either  , so all  were a brick-a-brack collection .

For me , vintage tube-audio has always been about classic look of glowing glass and stunning sound from a bygone age..

My DIY effort is a journey of many  tribulations,  but being able finally to enjoy the good sound of my gear  did repay back all the efforts and challenge.

I hope you enjoy the site, Thanks  .

Feel sure , I need your response to make this homepage better. I have a lot of mails and answering takes time and please do not feel neglected if my reply is short or delayed. I try to respond soonest.

Caution:

These pages deal with high voltages.
Contact with these voltages can cause injury and/ or death
both to you and what you land on after being shocked. 

    BE  ALERT  IN  EVERY  STEP , ACCIDENTS ARE ALWAYS AROUND THE CORNER !
 

You will need to have a relatively good  knowledge in the area of high voltage electronics since the devices displayed / discussed features lethal high voltage .

Currents of more than 20mA can be deadly! Not only touching may pose danger, at 300V or more a misguided approach is enough to make a spark accidentally arc from the device to nearest ground which may be yourself. Particularly dangerous are the direct and alternating currents with low frequency, for example the 50Hz frequency !

 At high voltage, when measuring and probing, even a separated transformer or ground fault circuit interrupter will not offer any protection! High voltage is only a jerk away and because it´s so unpredictable you have to plan ahead every step in the progress.

 Provide a clean and robust structure when putting the parts together!  All components should be clearly positioned so that no short circuits can occur. Check all the soldering and mountings for short circuits before connecting anything to the main power supply.

 Handling high voltage has to be considered without a doubt dangerous, so please NO guessing !  

 As an adult you will have to take the full responsibility for the building of the kit, for yourself while building the kit and for the operation of the completed kit !

I do not take any responsibility for future injury or death of anybody building the project or guarantee it´s function.

This is where the family enjoy the music. No dedicated room ,... our home is small and it also sounds egoistic to my wife.
