VIDEO RESTORATIONS  

 

  Aerodyne Swan

The Aerodyne Radio Company were based in London during the 1930s. Like many firms, they failed in the latter years of the decade, so effectively there was only around seven years of radio production. This video describes the complete restoration of a 'Swan' from c.1933.It appears that Aerodyne majored their sales through wholesale outlets. They may have had dealerships but so far I have not been able to verify this.

 

     
   

Repairing painted Bakelite cabinets

Many makers spray-painted their Bakelite cabinets during the post-war valve period and up to the transistor era. This was presumably to make the sets attractive and 'modern', to lose the heavy browns and blacks typical of Bakelite radio cabinets (white cabinets were made from Urea Formaldehyde, similar to Bakelite's Phenol Formaldehyde but not quite as durable and prone to spontaneous stress cracks).

This particular receiver appeared to have been used for target practice, to judge by the considerable damage. The video shows how Milliput plastic may be used to rebuild damaged and missing sections of the cabinet.

   

Major Maestro cabinet repair

The Major Maestro was Pilot's larger version of the Little Maestro and shared some of the same technology, such as the lack of a fully isolating mains transformer and a sturdy mottled Bakelite cabinet. This example was found to be missing a section of one of the loudspeaker grill bars and the video shows how this problem was solved.

   

Goblin 'Timespot' cabinet repair

These were substantial sets, post war of course. They incorporated a clock which I believe doubled as a timer to switch the set on and off. The clocks are usually useless and this one was no exception but the main problem was cabinet damage - a gaping hole in fact. The video shows how this problem was addressed. Note that although the chassis was fully restored, the video only covers the cabinet work.

  Marconiphone record player restoration

Record players became increasingly popular in the later 1950s and remained so until superseded by tape-based players. The simplest record player used a single player (motor, pick-up arm) with a single-pentode valve amplifier and a top-cut tone control. More expensive models might use an autochange record mechanism and a multi-valve amplifier, perhaps with treble and bass controls - though it has to be said that the boxes rarely allowed for a good bass response.

Many different makers produced very good record players, yet 'Dansette' models are the most sought-after. Quite why this is remains one of life's mysteries.
