Two monster power supplies.
Apc mrf2800 series. Datasheet is online, pulled from laser that burned wafers, you're looking at 100a current, adjustable from circa 18 to 30 volt, chassis isolated from output, two in series for some class A
Going cheap, space is not a luxury anymore

Here's a list of resistors.
If nothing is noted the resistor is a Philips mrs25 1% 50ppm 1/6w
The resistors are in random order, and there might be a few doubles.
Please dont ask me to count them, I will weigh them.
And I prefere a lot sale or at least combined with some of my other stuff.
Here we go..

Okay, total weight, is 7.93 kilos.
Data sheet states 200mg pr resistor, that amounts to 31680 resistors, taking in consideration bags tape, some power resistors, I think its safe to say that there's at least 25000 resistors.
Correct me if my math is off

A bit of audio topic.
Here are great load of photo transistors.
TiL31A and B
BPW77
And TIL81.
I checked them out on various web shops and they go for 5 to 10 dollar a pop.
Off course I'll sell much cheaper 😀

This one is a mess, I apologise in advance 
Here is a broad variety of silicium.
Old opamps, darlingtons, zeners, regulators optocouplers,diodes, counters,bridge rectifiers, stud diodes, thyristors, pwm controllers and so on...its a mess.
I can make a list if requested.

There's some nice things in there. i've been thinking about making a darlington based Linear supply. Have you got any left over after the lads above?
