Is a parts unit worth buying?

The $86.39 parts price is $78.61 less than the $165 working asking price — a 48% gap. Whether that gap covers the cost of repair depends on what's wrong.

What "for parts" usually means for a receiver: Receivers listed "for parts" usually have a blown fuse, dead channel, scratchy controls, or failed capacitors. Cosmetic issues (missing knobs, cracked dial glass) also land units in this category.

When it pencils out: A full recap from a competent shop runs $250–450 for most receivers. Single-channel failures are often cheaper — a bad transistor or blown fuse might be $80–150 in labour. If the gap between the parts price and working price is $78.61 and recap costs are $300, you're roughly break-even on paper — only worth it if you enjoy the restoration process or the unit has sentimental value.

When to walk away: A receiver with a cracked transformer, missing output transistors with no replacements available, or major physical damage (water, fire, rodents) is genuinely for parts only. Check listing photos carefully for burnt boards or missing components.

DIY vs shop: Scratchy controls and dead dial lamps are DIY fixes — DeoxIT and a lamp kit cost under $30. Beyond that, receivers need a bench and test equipment. Full repair cost context: what vintage stereo repair actually costs.
