Upgrading Naim Stageline phonostage

Naim Stageline is a joke of a  phonostage, but when combined with Hi-Cap power supply it gains both in weight and in price points. Once I switched from VirtuosoWood MM to a MC cartridge, “Stageline N” went into storage and “Stageline S’ took its place.

For my cartridge,  AQ 7000 Fe5 (made by Scan Tech = Lyra and periodically sent to Lyra for rejuvenation), “Stageline S” (470 Ohm load)  is recommended. My first  impression of AQ/Stage-S was that I should immediately revert back to Virtuoso Wood and Stageline N: sonically my Sondek became “dead”… Continue reading Upgrading Naim Stageline phonostage

The most beautiful Discman in the World. Loewe CD-100

Here is the Snow White:

 

It must have been kept in storage until the grease got stiff, then played… once! Sled gears were immediately broken and so the Sleeping Beauty was packed and stashed away for a few decades…. then posted on eBay.  I was the one who bought this beautiful paperweight.   Continue reading The most beautiful Discman in the World.

Nakamichi decks and OCD – Orange Caps Disease

Matured and well-nurtured obsessive-compulsive disorder (OCD) had pushed me towards Nakamichi decks. Beautiful TEAC A-100 was more than adequate for my needs of making tapes to be played through a boombox. But how could I miss the chance to buy Nak LX-3, and then LX-5? LX-5 was professionally calibrated for me by Willy Hermann, but LX-3 I decided to fix myself.  Getting $100 Service Kit from eBay member revox-de was the first step:

A few weeks of pain and suffering resulted in a beautiful-looking (and up to specs) deck:

Portable CD Players Components Composition

PCDP Components Table in MS Excel format

PCDP Components Table in PDF format

Original table can be found at kaosuncd.com. I transferred data into MS Excel and then sorted Discmans by the year.  Some info on Sony Discmans was borrowed from sonyvintage.com; other-times extracted from Service Manuals or from the photos of the actual items undergoing surgery on my workbench. Excel file is updated each time I get a new Discman, PDF file updated only occasionally

 

 

Philips/Magnavox D6800 restoration

D6800 shall never win any Beauty Contest: it is just too big and chunky. It was designed for portable use, and all 6xAA (!) batteries should be loaded inside the player.

As already mentioned here, D-6800 has one of the most powerful headphone amplitiers among Discmans. Officially it is rated as 20mW into 32Ohm, but my own tests show the same numbers as for Sony D-50MkII and Technics SL-XP5 which are  rated at 30mW/32Ohm.

Bad news: absolutely ALL D6800 are dead by now… Continue reading Philips/Magnavox D6800 restoration

Sencor S-4800 restoration

Boomboxes from Sencor are the only Swiss boomboxes out there. “Designed in Switzerland”, made most probably in Japan. Well, at least the label for Sencor S-4500 says “Made in Japan”, whether this applies to S-4800 nobody seems to know. By looking at cassette mechanism it may be easy to tell who made these boomboxes for Sencor: JVC, Philips, Sony,… I am not in the know, but maybe someone looking at the photos will be able to recognize the mechanism.

S-480 schematics can be found here: S-4800schematics

Here are my efforts to restore S-4800 to its original state, with a bit of extra beautifying: …
