Bush DAC10 (1951)

The DAC10 is very popular among radio collectors for its nicely designed Bakelite case. It is and AC/DC radio, using Mullard valves with Rimlock base.

The set uses Rimlock valves. The Rimlock base has been used from 1947 to 1955 by a few European valve manufacturers, including Philips and Mullard. They were rapidly replaced by Noval based valves.. The DAC10 has these valves:

• UCH42 as frequency changer
• UF41 as IF amplifier
• UBC41 as detector and AF pre-amplifier
• UL41 as output amplifier
• UY41 rectifier

They all have a 100 mA heater for series connection.

I bought this radio in early 2008 from a fellow collector, who was selling most of his collection to get more room in the house. He told me he had never used the radio, for him it had been a delicate piece of decoration only. The Bakelite case was a bit dull, but it looked well except for a small chip on the side. All in all, this was a nice buy.

On the inside, the radio looked complete and OK. The chassis was rust free and the dropper resistor and other components hadn't suffered from heat too much. It did have some dust inside, but not much. So now it is waiting for me to make it work again.
