Park amplifiers can essentially be regarded as "covert Marshalls" since they share everything except a few aesthetic features. This amplifier can be directly linked to the Plexi-era JMP50, as it shares the exact same Drake transformers and the 1987 circuit layout. The only difference lies in the Park 75's use of 6550 tubes instead of EL34s, providing increased power compared to the Park 50. This amplifier delivers a superb 50W Marshall sound, with a distinct bark from the Tung Sol 6550 tubes. At some point, the front logo and back panel were lost and have since been replaced. Most internal components have remained original, with some older changed filter caps, along with two 100k resistors and a modified bias resistor.
