Heathkit Trainers

These are very early op amps made with tubes.

Here's a real delicacy - an Unbuilt Heathkit.

If you were ever lucky enough to unpack a new Heathkit, you never forget the neatly wrapped packages of parts, the unpopulated PC boards. The shiny new chassis, and the greatest thrill of all, the unmistakable smell of brand new wire. You have to experience it for yourself.

Here are two different versions of the ET-3100 trainer. One is an original Heathkit, and the other is an OEM version.

This is the ET-3200 digital trainer.

This was my first processor - all 256 bytes. I had this one interfaced to my Paia synthesizer.
