Pre-war television electronics as far as the eye can see !  The first job will be to remove the valves and blow off the dust...


.. and also dust out the cabinet...

First I've got to get out the speaker board. This unscrews and slides down. However it then gets stuck, so I take out one of the side wood bearers - a very easy operation.

 Here's the speaker board and grille as seen from the front. These were generally lightly lacquered with the same walnut cellulose toner used on the cabinet. This gave them a more subdued 'glow' than the bright brass plating underneath.

I didn't know the above when I last cleaned this up in the '80s. But I shall be restoring it to its original appearance this time round.

 An 'add-on' that's always been on this set was a lamp switch someone had fitted to the rear. This originally had been used to control a back-light. I changed it to switch the EHT transformer on and off. I used this feature to save the tube from any switch-off burns.

Underneath, we see the serial number is '224'. Next, both this switch and the insignia are removed.

  Here's the warning transfer at the upper rear of the cabinet. As yet, I am undecided whether to work round this during cabinet restoration, or replace it with a replica transfer, scanned in and manufactured in-house. The problem will be reproducing the gold colouring of the letters...

 The next job is dusty, so the cabinet goes out of doors. The muck is blown out using the compressed air line. Following this, the cabinet interior is cleaned out with white spirit.
  This damaged internal sticker on the cabinet floor now becomes more clearly visible. I shall later be creating a replica electronically and replacing this.

  This transfer however I shall definitely be leaving alone !  It sits just below the screen. This screen panel is still in good condition and so will only be given a 'short' restoration. Then this panel will serve as a colour reference for when I'm matching the colour tone during the respray of the main cabinet.

  Here are the miscellaneous panels detached from the cabinet. Most will require stripping, repair, re-toning and re-finishing.

This valve-guide label will also be reproduced. It is stuck to an internal cathode ray tube shield, intended to be visible (obviously) when the rear cover is removed.

 Time to start getting stuck in to removing the worst of the ingrained dirt from the chassis panels !  I'm using a mixture of solvents at this point. Cellulose thinners is also good for this job, but then good ventilation is a 'must'.

  I've just removed all the valve screening cans from the TRF strip and am greeted by this view of MSP4s marching in step... rather beautiful I think.

I'm leaving on the coil cans for now to protect their delicate contents...

..which we see here. Here are just three of the RF transformers which are stagger-tuned during the vision alignment process. Since signal strength hasn't been an issue for the past 20 years - while operating this set from a converter/modulator - they're currently set to 'ultra-wide-band' spec (minimum gain) to give the best possible picture.

The coils are wound on most attractive formers of a crystalline plastic appearance. Anyone know what this material is ?  'Lucite' perhaps ?





 Now I turn my attention to the cabinet. This will be completed before the electronics are tackled. While the electronics are being done, the new cellulose finish will then 'bed in' and grain-pitting will probably appear.

After the electronics are finished I'll then return to the cabinet, to rub it down, possibly also applying a final 'fly-coat' first.

First, the easy bit... the 'short' restoration of those minor cabinet parts which are still in excellent condition and which won't be requiring stripping and preparing before receiving their new finish.
