For a different model number : just pick a couple of different value resistors, number of power MOSFETs and the max Vds type, change of transformer and lytic caps.
Rest is standard.

Haute couture prices, with a prêt-à-porter production setup.
As the Memisis 8 demonstrates (even standard L-angles).
The standard L-angles makes storage easy.

I think Jacco meant these (the lacquered version)

It looks like it has been repaired.
Have the repairs been done competently?
Why were the repairs necessary?

What I meant was that the green 10 ohm resistor is a metal oxide type made by Roederstein. It is no loger in production. A replacement may be Vishay WK/WR.

The blue caps are styroflex HF blockers, and the green res. are tubed metalloxide Withrom induct. free HiWatt 5% resistors.

If so, then they're low capacitance value.

TO-3 mounting hole distance is 30mm, heart to heart.
The body of the bypass caps under the board is less than half that.
Not 15mm is 11mm, 11mm means low cap value (70Vdc rails)

See : http://www.komponenten.es.aau.dk/fil...elle/KS429.pdf

For a size reference : 45300pF/63V Polystyrene EMZ - 3.3uF/100V MKC Roederstein - 2.2uF/400V MKP Siemens
