This morning I ordered 2 more super regulators...I will try them out ..one for the clock en one for the motor.....if it proves to be
disapointing to use on the clock I will give the NC PSU from Trichord themselves a try...

Today I took the entire day working on the copper enclosure....
details on the dutch forum...sorry

...a couple of days ago I made (with my friend ofcourse) a kind of weight compensation for the laser transport to solve the resonance and the free-friction on it...

Remarkable how it influences the sound for the better....by increasing the weigt you are able to "voice" ...it speaks for itself that this will continue as my final tweak....however I could not resist to build a more versatile crane for the final enclosure...

The foto shows a contraption made out of brass wire and a part from my miniature boating articles...quickly made to good use to give it a try...

The idea comes from Cees Pel (years ago) a very good friend of Wilco (VOID) who explained the boombox laser theory.

They have a 5 year further development of the Shigaraki on their resume..

The weight of 1 gram in action....(if you build one yourself try to lift the weight and notice how the sound changes.)...

...since for me hearing is believing I took the trouble of building a very versatile profi crane....ofcourse totally non-magnetic materials and silk wire.

Just out of curiosity I measured the current draw of the Shig. On startup it peaks briefly at 450ma and then settles in to 200-210ma DC while running. This was measured at the output of the 8v supply.

Q902 is where it is suggested that a super regulator be used.

The Q902 is a B764 regulator. It says that Collector to Emitter Saturation voltage is IC 500ma and IB=50ma. Base to Emitter figures are the same.

Anyone know what the figures mean?

This appears to be the correct datasheet.

What I 'think' this transistor does is 'regulate' the 8V supply down to 5V for the circuits that require this voltage.

Question. The black jumper wire goes from the + side of C916 to? I'm having trouble tracing it out.
