[R-390] R390A Parts by Sigmapert

[Glenn]

Hi List,

Yes, Kurt's, Sigmapert on ebay, parts are exceptional electrically and his workmanship with machining the various enclosures is also exceptional. I use his Capacitor, 3TF7, Diode and Balun replacements in all of my 390A restorations. 

The small tube like enclosures that look like tubes are actually machined down at the top to give them more appeal.  I am still puzzled about how he made the enclosures for the baluns. He even machines  the tube plugs which are now unobtanium for  miniature tubes. Nothing like Excellent German Ingenuity.

Kurt has several PhD's in medical fields and needed special electronic apparatus for his experimentation. He went back and got a EE so he could understand electronics to make his own equipment; that and he is a true gentleman to boot. 

I have done a lot of business with him and can only say VERY POSITIVE things about Kurt and his products. He's A+++++ in my book!!

I have no PECUNIARY interest in Sigmapert or his products; just acknowledging the integrity of the owner and his parts based on my extensive personal experience.

73,
