Any info or possibly a schematic of the setup with this Amp. Has a new board and twin Caps per side very different from the original.
Thanks in advance,

It's from Frank Van Alstine's company in Minnesota, which at one time was called Jensen's Stereo Shop. The model number suggests that the output is 75 WPC and the vintage is mid-to-late 1980s. If my experience with a later Van Alstine design (Omega II 240 from 1992) is typical, it should be a fine-sounding amp. I'd suggest contacting Frank directly if you want more information; the Web site at https://avahifi.com/ lists his e-mail as frank@avahifi.com and his phone number as 651.330.9871.
