Bush DAC90 Very early production model (1946) SOLD

The popular DAC 90 series started off with the 90 and was produced from 1946, though , the month when production started was July. 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 Bakelite case the heat given off by this, and therefore 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 noticeable. These first models have the speaker connected to its chassis, and later to aid in production costs the A series had this fitted separately, 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 ,all electrolitic capacitors, a number of cathode resistors were replaced. The I.F coils have been repaired as the cores had worked loose not allowing I.F alignment . All the valves were tested and 2 have been replaced with new old stock, the remaining ones are still perfect . lot of new wire around the HT side has also been renewed and then I.F and RF alignment undertaken, so its now good as it gets. Comes with its original 2 pin mains plug and 6 months guarantee.

The original speaker cloth has been replaced with a similar vintage style.
