Old Heathkits never die, they just get restored #Heathkit @nutsvolts

Nuts and Volts highlights the restoration of a vintage Heathkit EC-1 analog computer:

The Heath Company originally sold the EC-1 from 1959 to 1971 for $199.95. It had 17 vacuum tubes and lots of knobs and banana jacks in an awesome front panel. Above is a picture from the Heathkit catalog. Nowadays, they show up on eBay on a fairly regular basis, but some of them can be quite expensive at well over $1,000.

When I bought the computer, I knew I was in for a major cleanup after seeing the photos on eBay. At first, I thought that a little 409 cleaner would do the job, but I soon realized that I would have to completely disassemble it and unsolder every component in order to bring it up to my standards.

I was pleased with the result. The old metal cabinet had some light rust on it and I had planned on trying to match the original Heathkit gray wrinkle paint. After unsuccessfully trying a few automotive sprays, I went for the ultimate: a gray hammertone powder coat.
