[Collins] HP 410 b

[Mike Lord]

While aligning a KWM 2, the RF probe on my HP 410 B went out. The 2-01-c is open.  I've searched the internet and did find them available for $75 @ SSN.  That seems high.  I didn't pay but $100 for the entire unit.  Do any of you know of another source, or has anyone come up with an alternative?  I'm thinking of a modern diode affixed permanently in the probe and disconnect the 5 V.  Does anyone have a suggestion?  Thanks
