Not on the list?

Diagnosed & quoted

Receivers, 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.

Instrument-side gear has its own benches: guitar amps & pedals, synths & drum machines, and DJ & stage gear.

The gear that walks in

The units we see most often, and what their usual repairs run. Every number is a typical repair, not a promise: the exact quote comes from the bench after the $49 diagnosis, and the diagnosis is free when you approve the repair.

Classic receivers & integrateds

$100–$175

Pioneer, Marantz, Sansui, Harman Kardon, NAD, Onkyo, Technics. Dirty controls and cracked solder joints usually run $100; protection-circuit and component-level repairs from $175. Recaps quoted from $200.

CD players & changers

$99

Yamaha, Technics, Denon, Sony, and Oppo players: tray, belt, and lens service. A dead laser pickup is the bigger job, typically around $179 all in with the part and alignment.

Cassette decks

$150–$300

Tascam, Yamaha, Nakamichi, and Denon: belts, idlers, pinch rollers, and adjustment. A full transport service with calibration sits at the top of the range.

Turntables

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

Recap work ships with before/after measurements. If we can hear it, we can show it.

Brands we know cold

McIntosh, Marantz, Krell, Luxman, Pass Labs, Accuphase, symptom patterns and common failures from thousands of real repair discussions and bench records.

The honest answer, free

Sometimes the right call is "don't spend money on this." We'll tell you when, and you won't pay to hear it.
