stereo cassette deck ('77-'80)  $1100 recapped / restored

In absolutely mint cosmetic condition, recapped and restored, this Marantz 5030 stereo cassette deck comes with the service / data sheets and old parts.  As shown in the photos, one of our optional, custom-built, solid walnut covers is also available.

NOTE:  What are the actual differences between the Marantz 5030 and the 5030B?  Essentially, on the inside they are both identical.  The main difference is the actual physical size of each deck.  The 5030 is the same size as the Marantz 2270 and the other 22xx series of receivers.  The 5030B is a bit smaller to match the dimensions of the Marantz matching components; an example would be the Marantz 1060 integrated amp or the Marantz 250M amp.

Services performed (February 2026):
Repair: Replaced meter lamps with Cool White LED and tape indicator lamp
Strip, clean and apply Lithium grease as required tape to transport chassis
Replace all belts (3)
Replace Idler Assembly FF/RR - 19x15x3 tire
Replace Take Reel - 19x15x2.5 tire
Replace Drive Idler -19x15x2 tire
Clean all switches and controls with De-Oxit Fader lube or G5 as appropriate
Demagnetize heads and spindles
Replace all electrolytic capacitors on P900 Power Board
Perform adjustments per the Service Manual
NOTE: Record Bias is set with FeCr tape so Record/Playback is optimized for FeCr. There are no individual adjustments for STD or CrO2

Key features would be its wide bandwidth and the convenience afforded by the 3-head format and master level fader.  Of course there are many other features on this incredibly well designed deck.

Three-head decks like this 5030 give you off-tape monitoring and, generally, increased bandwidth. Marantz managed to wrap a separate playback "head" with many other desirable features into an attractively priced package of $470 in the late 70's. Here the electrically separate recording and playback elements are combined physically into a single head assembly, a technique that increased in popularity because it made user adjustment of recording-head azimuth unnecessary. The recording and playback sections were fabricated from hard permalloy; the erase head is ferrite. A single DC motor powers the transport.

Separate concentric controls for the microphone and line inputs permit source mixing. The two elements of these controls, which serve to adjust channel balances, rotate independently; the MASTER control increases or fades the recording level of both channels at once (a welcomed feature!)  The recording level appears on two large averaging meters that are clearly illuminated by backlighting, the "safe" area (-20 to 0 dB) in blue and the "danger" area (0 to +6 dB) in red.

The meters are aided by a pair of peak-responding LEDs that trigger at about -10 on the meter, depending on the high-frequency content of the program material. Either the input signal or that from the tape can be routed to the output via the MONITOR switch, the mode being indicated by another pair of LEDs. The multiplex filter can be defeated via a rear-panel slide switch.

The cassette-loading mechanism operates smoothly, and the front door can be removed for fairly good access to the heads for cleaning and demagnetization. You can go directly from a fast-wind mode to PLAY without pressing the STOP, but we would discourage such practice, because the deck can throw a tape loop under these conditions and might jam. The pause introduces no audible click but does create a short-lived speed perturbation.

Although there are many types of cassette tapes available, TDK SA is highly recommended as per many online tests performed with various tapes.

stereo cassette deck ('75-'78)    $600   recapped / restored

This lovely Marantz 5420 stereo cassette deck was completely restored and strategically recapped in October 2025. 
NOTE: All the service work was performed by our associate "master tech-engineer" who once worked directly for Superscope / Marantz and also has over 30 years experience in the field of electronics.

The Model 5420 cassette deck was (still is) a phenomenal piece of engineering. The Marantz/Superscope design team built a solid cassette tape mechanism that includes dual recording source input and output, plus a "panpot" recording redistribution capability that is quite versatile and fun to use. Excellent analog monitor viewing capabilities, and a nice console design for comfortable control of recording/playback functions.

Service included the following:
~New power switch assembly
~recapped power board
~New belts
~Transport mechanism, tires & mating surfaces lubricated with lithium grease
~Cleaned and demagnetized all heads & spindles
~Verified speed, azimuth and general operational specs

The Marantz 5420 is best described as being lavish, luxurious, wide, large, lit-up and tall.  It was unique and different from the other Marantz decks. It has a full-size 4-channel mixing board complete with master fader and panpots and a Dolby function which could be used internally or externally with another source or even a Dolby-compatible FM tuner or receiver.

The stunning enclosure and finish are certainly the most striking elements of the 5420; the topside design includes large and sexy VU meters with peak level LEDs and a 20° up tilting top panel...plus a FeCr tape position and Dolby calibration pots. 
Underneath the unit is a cleverly tucked away fold-out stand that tilts the deck in a more convenient "studio" position for easy access.

Here's the link to High Fidelity magazine magazine review (April 1976) of the Marantz 5420:

NOTE:  Smaller siblings included the Model 5400 (sans Dolby), 5220 (frontal loading), 5200 (a 5220 sans Dolby) and 5120 (a 5220 in console type)

Wow & flutter 0.07%

REW time: 96 seconds

(2013)   $1400  (includes factory remote / documentation & box)

In mint cosmetic and operating condition, this beautiful Rega Saturn-R CD player comes with the original box, factory remote and documentation.

From "The Ear" (HiFi Music website):

The phrase is ​a game changer. This is not a CD player as we know it​ (with the possible exception of the ​$​8000 Rega Isis​). No​t​ much has been heard in digital audio that delivers resolution and musicality in such convincing and entertaining fashion as the Saturn-R.

The Saturn-R, listed at $2200, is extraordinarily revealing and, more important, has the best timing in the business. What’s its secret? After all the Apollo-R has the same mechanism – a device made for portable use with a decent amount of RAM so that it carries on playing if it’s jogged. The DAC is different, it’s a Wolfson and they’re pretty good; Designer Terry Bateman says it's essentially down to power supply and housekeeping, there is more space in the box and more budget so things are done to a higher standard.
The Rega has managed to refine that and reveal more of what it gets off the disc.

It’s also worth mentioning that this is also the best DAC that Rega has made (it has asynchronous USB f​or instance) even if you wouldn’t guess it from the front panel. But stick what you will into its digital inputs they won’t beat the onboard source, must be a clocking/jitter thing.

Specs:

Digital inputs: 2x optical, 2x coaxial, Asynchronous USB
Digital outputs: 2x coaxial
Outputs: single ended RCA phono
Supported sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 192kHz
Dimensions (H x W x D): 3.2"H x 17"W x14"D
Weight: 23 lbs
