[sdiy] things to scann

[Czech Martin]

-I found the headphone amplifier. I think it is a class A discrete.
-I also found the schematics of a Keithley pA-meter from '77.
Still interesting for me. J.H.: you where right in this respect,
you'll see...
-And I have the power line transient absorber/filter

Ok, I'm on business trip this week, but I try to scann this stuff and put it
on my site. It's under construction anyway.

Please be patient.
