Model 400 was introduced in the fall of 1963 as a 1964 model, along with the then-new 500-C and 800-C. The 400 was sort of a stripped-down 500-C, an "entry level" stereo receiver compared to its bigger brothers, the 500-C and 800-C.

It is unusual in that it uses four oddball magnoval audio output tubes, the 7868.

I found mine in May 2016 at Kutztown. Here's a picture I took of it as soon as I brought it home.

Since I took that photo, I have replaced the two missing brass knob brights, but had not done anything else to it. In spite of knowing better, I did try it out with headphones...and was thrilled to discover that it worked!

Did you notice something wrong just to the left of the headphone jack, just left of lower center?

Here's a closer look:

And a look inside at the same broken switches:

So the challenge was...what to do about those broken switches?
