Is a parts unit worth buying?
The $165 parts price is $2,463 less than the $2,628 working asking price — a 94% gap. Whether that gap covers the cost of repair depends on what's wrong.
What "for parts" usually means for a reel to reel: Reel-to-reel decks listed for parts may just need rubber: a pinch roller, idler wheel, or belts. Or they may have worn heads, seized mechanisms, or missing parts that are now unobtainium.
When it pencils out: Rubber replacement (pinch roller, idler, belts) is the most common and most fixable failure — parts exist for most machines and labour is $100–250 at a specialist. The $2,463 gap makes rubber restoration financially sound if that's the diagnosis.
When to walk away: Worn heads on a reel-to-reel are expensive to replace — $300–800 for most machines, if replacements exist at all. A deck with head wear plus mechanical issues is a project that easily exceeds its working value.
DIY vs shop: Reel-to-reel service is specialist work. Belt replacement is manageable for someone mechanically comfortable, but anything involving the transport mechanism or head alignment needs proper test equipment. Full repair cost context: what vintage stereo repair actually costs.
