'PEOPLE'S SET' model 444
of a series of so-called "People's Sets", a term generally
assumed to have been used because of the supposed similarity between the
Bakelite cabinet versions of the set and the rear window of the
Volkswagen (People's car). The release date of the 444: 1936. The
chassis is a three valve
‘short’ superhet with only one tuned IF stage and an output valve
doubling as detector and AVC. The mixer is of the self-oscillating type
and IF trimming is by compression capacitors. AC mains, full-wave valve
rectification. ME loudspeaker. Two waveband, no tone control. Bakelite
was sound with no cracks or severe scratches but it was very dull and dirty.
The grille cloth damaged, badly soiled and
rotting. There was no rear cover. Surprisingly there was little rust on chassis metalwork, but
it was very
dirty and encrusted with a greasy layer.
At some time, additional loudspeaker leads had been fitted, not
very expertly. The pointer on the scale was in the wrong place on the
spindle, rendering it invisible in
use. The two halves of the tuning gang capacitor had been wired
together; a common misconception, where people mistake a 'wire wrap'
low-value capacitor for a broken soldered joint, even though common
sense should suggest that a twin-gang capacitor should remain so. The knobs are on the wrong spindles.
All the foregoing indicated that the set had been 'got at' by an
inexpert someone, previously. Illumination of dial
seemed weak. The tuning gang and dial assembly was loose. Main smoothing
capacitor, which should be visible above chassis, was missing. One of the
special chassis securing bolts was also missing.
Almost 100% output on pentode section. Both diode
Although output was satisfactory on both anodes, some
worrying ‘flicking’ of the tester meter needle indicates a problem.
I.F.amplifier: Low emission.
Accordingly, new valves fitted were Mixer/oscillator,
I.F. amplifier and rectifier. Output valve was useable.
examination and work.
control dismantled, cleaned and reassembled. Wavechange switch cleaned.
incorrect double reservoir and smoothing cap that someone had fitted by
hanging dangerously in the wiring beneath the chassis was removed and a
correct metal tubular replacement capacitor fitted to original clip. New
mains lead fitted, using a new grommet and a restraining clip. New mains
Replaced components include C8 (HT RF bypass), C11
(LF coupling), C5 (V1, V2 screen bypass), C12 (V3 pentode cathode-grid
decoupling), R6 and R8 (
AVC coupling resistors). Replacement rubber washers
bonded to screw plates in chassis corners. General clean-up.
realignment of RF and IF stages was carried out. An Advance signal
generator was the signal source via a dummy aerial and output was
measured using an Avo model 8 as an output meter.
Above chassis work.
Chassis metalwork degreased and cleaned. Valve
screening cans cleaned. Valvecap connecting leads replaced/repaired.
Incorrectly linked tuning gang wiring returned to originality. Tuning
gang and scale dismantled and cleaned. New rubber bushes for tuning gang on reassembly. New
dial lamp and wiring. Damaged loudspeaker cone repaired. New
fabric fitted to baffle board. Knobs and cabinet degreased and polished.
