The Ultimate Old School 50 Watt Cheater Amp - US Amps VLX-50 or is it?

What we have here is what I’m told is a US Amps VLX-50. The amplifier is polished aluminum and in near MINT condition. Now, the question is how do we know this is a VLX-50? There’s no markings other than a serial number and US Amps logo silkscreened on the circuit board. I just looked closer and the amp has (12) 50v 1000uf caps for the power supply and (10) 25v 2700uf caps for the input filtering. Anyone who has a manual or any additional information about these amps, please let me know. I’m intrigued to
