DAC90A Wavechange Switch - UK Vintage Radio Repair and Restoration Discussion Forum

Hi All,

I recently restored a Bush DAC90A, however, during the restoration, I discovered that the wavechange switch was mangled. Unable to obtain a replacement original switch, I came up with an alternative. I bought a 2 pole 6 way rotary switch from Maplins (price £2.29). It is a tight fit, but works really well. The pictures below show the switch in position and how the connections are made.

I hope its useful.

Gordon.

There are many request for DAC90A WC switches on the forum. I am sure this is worth knowing, and should help a lot of people in the future.

Guys,
My apologies, there was an error in the diagram for the replacement wave change switch that I posted some time ago. The 2nd tag should have read TC2 and NOT L2 as shown in the original diagram. I have attached a copy of the revised diagram showing the correct connection.
