Da Vinci DVAS/Magnatone Troubador

The listing

Here’s an early 60’s (1962?) Magnatone Troubador 413 branded as “Da Vinci.” From what I’ve read, Magnatone/Estey would produce OEM amps for music stores under various brand names, such as Da Vinci, Panoramic, Tonemaster, and Americana. The amp works well, though I am unsure of its service history. The speaker is possibly a period correct replacement, and there is a three prong power cord.
