Default KW.E.a back to life

After just a good cleaning and fixed some tube socked ground connections (as explained by LA6NCA in his page) the old Anton came back to life, capacitors are still to measure and many minor issues are to be fixed, but this was a great joy indeed!

Good job! This is a tough and complex receiver to restore. I had to open almost every LC box on mine to loosen up the ceramic trimmers to tune the set to the best performance.

Here's some documentation for the one that I restored:

Thank you Yuri,

congratulations for your outstanding calibration job, very useful pages.

I am a little bit afraid to cause some damage to the RF stages doing such a complex job, anyway I will read carefully your experience and after I've done some measurements I will decide about it.

In the meantime I have reproduced the rotary switch panel with a 3D printer but I have problems with the small writings. While printing the hot material fills the too small letters voids, may be I'll try using a more hard plastic.

Best regards

Andrea.

I know, it give a buzz when things come back to life again. I am doing a lot of radio restorations at the moment, so far one transceiver, two transmitters, three receivers and assorted power supplies done this winter. Time to join Radioholics Anonymous....

regards,
