the modder's diary (don't remember the last number, so let's restart with 30) part 30:
thinking of what to do next and tired of always carying my equipment with me from and to the office, i thought it is time for a tu-05 rebuild for my office:
tube section and output transformers:
here with most of the components:
i think i will call this rebuild "SilverStar I" (any better suggestions?) as there are a lot of silver shining components, and it will have a central ground star topology.
the resulting amp will be a little silver cube:
- no battery needed
- with integrated HRT MicroStreamer USB DAC
- the hole amp will run completely with USB power
- only one USB port needed
- any USB power supply or USB power pack can be used
in the office you can just plug it in an USB port of your computer and listen to the music stored there!
as you can see a lot of power filter stages added, only the best components (WIMA MKP10 capacitors, mica capacitors, ELNA SILMIC II and NICHICON MUSE electrolyte capacitors and shielded, gold plated tube sockets). The pcb prototyping boards i use for this and will use for all the other builds i have planned are RF/HF prototyping boards, very expensive, but double layer with a complete GND layer one the top side.
the output transformers are really small, silghtly less good sounding than the original ones, BUT with very large impedance range, can drive anything from 4 ohm to 2 kOhm (and so for example also my HD800 or even a Beyer T1).
