Diagnosed & quotedReceivers, tuners, reel-to-reel, console-era gear — if it has a circuit and it matters to you, bring it. Free diagnosis when you approve the repair.
Built for the gear you keep
The audiophile bench is different: these aren't disposable devices. They're worth fixing, and they deserve the honesty that comes with that.
Almost always worth repairing
A $500 amp with a $150 repair is a no-brainer. Vintage gear especially — the replacement costs five times what the repair does, if it exists at all.
Measurements, not vibes
