Is a parts unit worth buying?
The $175 parts price is $1,825 less than the $2,000 working asking price — a 91% gap. Whether that gap covers the cost of repair depends on what's wrong.
What "for parts" usually means for a amplifier: Integrated amplifiers listed for parts commonly have one dead channel, blown output stage, or failed power supply caps. Sometimes it's as simple as a bad speaker relay.
When it pencils out: Output stage repair runs $100–300 depending on whether replacements for the output transistors exist. A full service is $200–400. The $1,825 gap here makes repair financially reasonable if the amp is confirmed repairable.
When to walk away: An amp with a blown transformer or no available output transistor replacements is a parts donor, not a restoration candidate. Ask the seller what failed and whether any repair was attempted.
DIY vs shop: Speaker relay cleaning and fuse replacement are accessible DIY tasks. Anything touching the output stage needs a proper bench setup. Full repair cost context: what vintage stereo repair actually costs.

Buying notes
DC-coupled Marantz integrated. The DC-coupled output requires DC offset verification before connecting speakers; elevated DC can damage tweeters. Recap $230-360. Good build quality; the DC design is more sensitive to capacitor drift than capacitor-coupled competitors.
