Professional Full Recap & Service — 617HiFi

This Harman Kardon 930 Twin Powered receiver received a professional full recap and service by 617HiFi in Brookline, Massachusetts.

The internal photographs included with this listing document the actual receiver and the work performed.

Visible service work includes replacement electrolytic capacitors across multiple sections of the receiver, including power-supply and amplifier areas and work around the large filter-capacitor section.

An LED illumination upgrade was also installed.

FM Tuner Disclosure

The built-in FM tuner remains nonfunctional.

617HiFi evaluated the tuner during professional service, but it could not be successfully repaired.

We are disclosing this prominently so buyers searching for a fully recapped Harman Kardon 930 understand the exact operating condition before purchasing.

For owners planning to use the HK 930 with:

• Turntables / vinyl
• Streamers
• External DACs
• CD players
• Tape decks
• Auxiliary sources

the nonworking FM tuner may have little impact on normal listening use.

BASH Vintage Audio Preparation & 3+ Hour Bench Test

After professional service, this Harman Kardon 930 received our normal BASH Vintage Audio preparation and testing.

• Faceplate carefully cleaned and detailed
• Knobs cleaned and polished
• Controls and switches cleaned as needed
• Exterior surfaces cleaned
• Accessible chassis areas detailed
• Phono input exercised
• Auxiliary input exercised
• Left and right channels tested
• Speaker outputs tested
• Controls and switches exercised
• 3+ hour bench and listening test
• Retested immediately before shipment

We do not simply power on a vintage receiver and call it tested.

Our process is designed to exercise the receiver under real listening conditions and identify obvious operational issues before packing and shipment.

Cosmetic Condition — Very Good

The front presentation is excellent and is one of the strengths of this HK 930.

The faceplate, dial area, knobs and controls present very well and retain the understated appearance that makes classic Harman Kardon receivers distinctive.

For the receiver as a whole, we are conservatively grading the cosmetic condition as Very Good.

The top cover, side panels, side trim and rear show visible age-related cosmetic wear, including scratches, scuffs and handling marks.

Please review all photographs carefully.

The photos show the actual Harman Kardon 930 receiver you will receive and are considered part of the description.

Harman Kardon 930 Twin Powered Design

The Harman Kardon 930 is one of the better-known receivers from Harman Kardon's classic Twin Powered era.

Its distinctive architecture uses separate power transformers associated with its left and right amplifier channels rather than a conventional single-transformer receiver design.

That engineering approach is a major reason the 930 remains sought after by collectors and vintage audio enthusiasts.

For a dedicated two-channel system, the HK 930 pairs naturally with sources such as:

• Turntables
• External phono sources
• Network streamers
• DACs
• CD players
• Tape decks
• Other line-level audio components

Please note again that the built-in FM tuner on this particular receiver is not operational.

Internal Photos Document the Full Recap

We have included extensive internal photographs of this exact Harman Kardon 930.

For buyers comparing a fully recapped HK 930 with unserviced or partially serviced examples, these photos provide useful documentation of the work performed.

The photographs show:

• Replacement electrolytic capacitors across multiple circuit sections
• Power-supply service areas
• Amplifier sections
• Large filter-capacitor area
• Twin Powered transformer arrangement
• Internal chassis condition
• Technician measurement and service markings

These are photographs of the actual receiver being sold, not representative service images.

Why Buy From BASH Vintage Audio?

At BASH Vintage Audio, we focus on accurately represented vintage stereo equipment.

We believe buyers should know what has — and has not — been done to a vintage component.

When we describe a receiver as professionally serviced or fully recapped, we provide supporting details and internal photographs whenever available.

Every receiver is carefully cleaned, exercised and tested before shipment.

We also take packing seriously. Vintage stereo receivers are heavy components, and even properly operating equipment can be damaged by poor packing or rough carrier handling.

Shipping

This Harman Kardon 930 will be carefully packed for shipment.

• Receiver carefully wrapped and protected
• Controls and faceplate protected
• Proper internal support to minimize movement
• Double-boxed where appropriate

• Signature confirmation when appropriate
• Shipped using a Reverb shipping label / applicable Reverb shipping protection

The receiver will be retested immediately before packing and shipment.

Please retain all original packing materials until you have fully tested the receiver.

Returns / Shipping Damage

Any authorized return must be coordinated through Reverb.

If shipping damage occurs, please contact us promptly through Reverb and retain all packaging materials.

Photos of the receiver, shipping carton and packing materials may be required for an insurance claim.

When a Reverb return label is required, processing may take approximately five business days.

Any returned receiver must be returned in the same condition in which it was received and should be repacked using the original packing materials.

Please Read Before Purchasing

This is vintage electronic equipment.

Although this Harman Kardon 930 has been professionally fully recapped, serviced, cleaned and extensively tested, vintage electronics should not be expected to behave exactly like newly manufactured equipment.

We make every effort to describe both operating and cosmetic condition accurately.

The primary known functional limitation is:

THE BUILT-IN FM TUNER DOES NOT WORK AND COULD NOT BE SUCCESSFULLY REPAIRED.

Please purchase with that limitation in mind.
