Very nice clean example of the popular Bush DAC range this being the early version in Walnut finish, as it is not in black this must be a later production run as this fits in with the later A
version and I would place this around 1948.
The popular DAC 90 series started off with the 90 and was produced from 1946, though i cannot find a month when production started. As the A version was produced in 1950 these were soon upgraded
and the reasons why are offered here. First of all the larger mains dropper was installed to the rear and perhaps this was to reduce in the Bakerlite case the heat given off by this, and therfore
reducing stress. The valves installed at this time had lower heater operating voltages so clearly the mains dropper resistor to reduce the voltage down would have to be quite large in size, within a
short period higher heater voltage valves were produced and helped to aid in the reduction of the size of this resistor and was installed in the new A series away from the rear cover. The tuning
control is fitted on the right hand side and is fitted to the tuning capacitor via its long shaft through the MW and LW aerial so pending stray capacitance from your hand it is possible to notice a
slight alignment movement of the signal as your hand moves away from this, though slight,perhaps on weak stations this might be more noticable. These first models have the speaker connected to its
chassis, and later to aid in production costs the A series had this fitted seperatly, again the speaker grill here cloth in this model was replaced with a punched out metal grill, (more cost
effective). And just a matter of interest , the pilot lamp used for the display was fitted in the centre only, while the A series models had two one either side.
That aside of the historic development, how does this radio compare today. It was a hit then and these little radio's are still sought after today, it works very well indeed and as standard all
de-coupling components replaced, the on off/volume control is new, replacement fitment to the rear cover and all valves tested and I.F and RF alignment work undertaken. Comes with its original 2 pin
mains plug and 1 years gurantee.
The photo below shows what a first class chassis this one has. So never been stored in a shed or garage, often these are full of rust.
