Hi guys,
My main external exams are almost finished and I need to get these stuffs away to clear out my room overwhelmed with electronic stuffs
Please e-mail me for photos, because somehow the forum doesn't allow me to post any pic in big enough size to be 'visible'
All prices are negotiable.
----------------------------------------------------------
The following descriptions are in order of the stuffs shown in photo, left to right.
*1x almost finished ETI-480 amp, with power transistors. I found this one long time ago, with a few of burned resistors on it. So I replaced every single component with new ones....
I've never got to finish this amp though... Because of my new interest in tubes...
*1x same ETI-480 board with some components on... All the caps mounted on it are either ROE or WIMA, even the electrolytic...
*1x unknown (better to say RANDOM) amp with heaps of different components on (has ROE caps on). I don't have any info. about this.
All together for $20

2x Diecast cases, top lids have many holes, but the bottom base pieces are almost perfect, except 2 little holes drill on one side. The two little holes are visible in the original high q. pic, but won't be visible in this tiny low q. pic....
Together for $2, but free to anyone who takes many stuffs.

A Sanken (Japan) hybrid chip based mono amp mounted on a heatsink.
This hybrid chip is known as the origin, the mother of all STK chips made by Sanyo.
This is truely the first hybrid amp chip ever designed. This one still works well!
It is impossible to source this chip these days... Been out of production for over 20 years!!
It is a historical stuff I guess....
Some spec:
Chip #= SI-1020
Max RMS power= 20W @ 8ohms
Supply V= can work on both single polarity or dual (single polarity= 46V, dual= +/- 23V)
Absolute max V= 55V or +/- 25V
Freq. range (Po=1W) = 20Hz~100KHz
More specific datas and application circuits will be provided to the buyer...
This one for $7
