Kenwood KR-6400 Value & Price History
As of 2026-09-21, a Kenwood KR-6400 has a market value at around $19, parts units around $225. Based on 27 estimated sales.
Is a parts unit worth buying?
The $225 parts price is $75 less than the $300 working asking price — a 25% 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 $75 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.

Buying notes
125-watt Kenwood receiver. Solid build from the silver-face era. Recap $260-400. Check both channels and tuner sensitivity. Kenwood receivers of this period are underrated relative to Pioneer and Marantz; often better value for listeners who don't need the badge.
