Is a parts unit worth buying?
The $397 parts price is $125 less than the $522 working asking price — a 24% 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 $125 gap here is tight — only pursue if you have a specific diagnosis and repair quote in hand.
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
EICO tube amplifier kit. Build quality varies with the original assembler; inspect solder joints carefully. Tube complement condition. Check both channels at matched output. EICO equipment is undervalued relative to the Fisher and Scott equivalents; good performers when properly built and serviced.
