    I just picked up the Eico 950B off Ebay last week. I had to re-cap it and some of the resistors well out of spec. After replacing everything the unit is working great and I even found a spot for it on my desk (I had the same concern as you, no space). It's a great piece of kit for testing filter caps in vintage radios and such. I'm glad I was finally able to get one. Great vid! Cheers!

    I just hope that when i get old somebody cleans my bits and keeps me working. 🙂

    The way i've 'retensioned' ccontacts is to put a small flatblade screwdriver between the head of the rivet and the raised part of the contact, give the screwdriver a gentle twist to push the bend away, this also works for wiper contacts Just check if the rivet is tight before you do this.

    It's time for a larger bench. 😎

    The tan days of Heath (1969-70 era) were the best of them, as I have the complete bench set. I believe they came out before Zenith purchased them. Sadly, Zenith was their downfall.

    Nice fix Scott. BTW did you ever test the valves in the capacitor tester?

    On other models I've seen you have to 'hold ' the leakage switch down and as soon as you let go it springs back into the 'discharge' setting, which is a great idea. My point being is this model without this feature or is it bust ?....cheers

    Does not have that feature. It is a 3 way switch. Telecaster style.

    Yes, and I still haven’t got a shock from them.
