Do you know why there are all thes +digit numbers on the ICs transistors

electrolytics ?

No idea about the electrolytics. On the semiconductors, it's the marking
for production month and year (but I don't have the code handy).

the 2 main TO3 output Tesla devices are marked KD607 but also X69321

The KD607 is a Czech npn power transistor, 10 A, 80 V, 70 W, designed
for AF power amps.

Never trust an operating system you don't have sources for. ;-)


I only have one German data book , ECA from 1987 and it does not list the
final uncertainty.
An E-line size or varicap type package of a diode marked 32 VV or 32 YV, 32
volt zener ?
