Eico ST40 Stereo Amplifier Restoration 

My father built one of these when I was a little boy. I was impressed then and still am. I listened to this amp a lot as a teenager. It eventually got handed down but not to me and I've lost track of it. Thanks for the look inside.

Really much better sounding than I would have expected. Another solid video really surprised you don't have a bigger subscriber base. Thanks, and Please keep up the good work!

You want to stick with using speakers made for tube amps only-high-efficiency speakers like the pair that came with the tuner and amp. Better for by the amp’s long term health and better sound Terrific resto, Adam

Hard to believe it's one year older than me! Worth $300 now that it is almost restored but use some better speaker to get it really singing.

There is a popular Loudness Mod for the ST40 on the tube amp boards Mods for the PEC Modules as those can lead to failures

Figured it out, thanks

Eico ST series have good sound if you can live with the hum at idle.
