Yes, but compared to the tons of rust that it had before...

I'm glad its looking pretty decent. The front hood can be re-chromed at some point, although I will probably leave it as is. The RF chrome deck has a lot of corrosion and I have several ideas on how to improve the appearance. One of them is to custom cut a piece of brushed metal to cover the pitted areas and perhaps recreate the original lettering on it.
So, in 8 months I have:
- cleaned the unit
- Painted tube shields and transformer
- replaced optocouplers
- Replaced critical signal caps with original Siemens replacements and Vitamin Q oil caps.
- Replaced all four front wafer switches
- Replaced front panel and knobs
- Rebuilt power supply with miniaturized modern caps concealed inside the old cans. New SF4007 high speed Fairchild diodes. New Old Stock bleeder resistors. German F/T electrolytics in the negative supply.
I still need to replace most potentiometers in the scope circuit.
In all, a lot of work, but the results have made it quite rewarding in the end!
