Altec 1570-B monoblock 811 amps completely upgraded with extras

Another one of my audio treasures offered for sale. This time it's a pair of Altec 1570-B mono block amplifiers, completely upgraded by the tech that worked on my Futterman amps. Rather than going the more common upgrade route, we decided to keep the bank of rectifiers. I replaced the plain (non-metered) front panels with thick plexiglass. The safety switch (which shuts down the amps if the cover is removed) is still present on both amplifiers.

Amps have seen very little use. Sale includes a ridiculous amount of 811 power tubes, rectifier tubes and signal tubes, all having been rigorously tested and matched with Amplitrex and RoeTest printouts included. You are purchasing a PAIR of amps. Some of the detail photos only show one amp and this is for the sake of brevity.

Amps are located in Hillsboro, Oregon.
