1954 Ferrograph 2N
Back to gallerySpecifications

I bought this machine in 1987 from a music teacher who had used it for "ear" tests for his pupils.  He had owned and maintained it since new and was now retiring due to ill-health. 

I paid $AU 50 and it came with the owners manual, original Ferrograph locking reels and Reslo-sound ribbon microphone.  He also had an old valve mono disc lathe and a mint condition Hammond B-3 organ with Leslie speaker ($300 for the lot! - my wife said NO WAY!!)


With the help of Guy White at White Noise Electronics here in Sydney, the 2N has just undergone a major overhaul with new capacitors throughout,  new valves, VU calibrate pot, counter drive belt, a very thorough cleaning and head re-alignment.  It sounds and records just like new and should last another 30 years although the rubber capstan will need renewing in the next few years.

The Series 2 was released around 1954 and was the first Ferrograph for the domestic market.

For the next 15 years or so, right up to the release of the series 7 in the late 1960's, all Ferrograph models featured the same large, circular function knob (the design of which changed only slightly).  

One selected the desired function and activated it via a small adjacent lever.  A spring loaded button next to it would stop the machine with a loud ZINGG!.  

This was NOT a subtle activity. On my Ferrograph, it requires considerable effort to turn the function selector knob, even though it has been well lubricated.

The meter was for record level only. It sat hard over to the right hand side until record was selected, then slowly swung to zero. One could then adjust the meter to absolute zero via the trim-pot directly beneath it before checking record levels.

To the right of the meter are the bass and treble (playback) controls and to the right, the gain control for both record and playback.  The dummy knob on the far right covers an octal auxiliary socket.

The power supply and audio amplifier sit on the bottom of the case and can be quite easily accessed.  The tape deck is held down by two screws and hinged at the back.

By removing the screws the entire deck can be lifted up like the bonnet of a car.  All connections are via the two purple braided cords seen at left.

The single Goodmans 10" x 6" speaker sits on the right hand side of the case, next to the power supply and amplifier.

There are additional images,a user manual (60pages!) and a circuit diagram for this recorder on the CD-ROM
