Having had previous experience of both a Bush AC91 and a Bush DAC90A I'm hoping that this will stand me in good stead with this DAC 10?
Before starting any work, I have of course read most of the previous Forum Threads here on this popular set along with other online resources including YouTube videos.
External case in good condition apart from a crack to the rear of the Pre-set button panel - but that's for later. The Pre-set buttons were in a very poor state but Forum member
Northyorks1 has very kindly provided a full set of replacements in extremely good condition - thanks!
Managed to extract the chassis from the case and there is very little sign of anyone being in there recently - good news. It's a bit of a rust bucket in certain areas but I won't know the full extent until I clear away the dust, cobwebs and other detritus!
Some early pictures:-
I have a slight conundrum with the mains cord as I am measuring 77.4Ω between the chassis and the LIVE (Red) wire and 1.46kΩ between the chassis and the NEUTRAL (Black) wire. I expected the values to be the other way round so may suggest that the switch is connected up the wrong way round?? All measured values throughout this thread are made using my ToolZone DMM - my AVO 8 is still on the To-do list.
The good news, however, is that the Output Transformer seems o.k. with 569Ω on the Primary and 0.8Ω on the Secondary.
And we are getting some crackling from the speaker when measuring theses values.
Now what to do about that rust - a great number of Threads have already covered this and I am favouring Hammerite 'Kurust' at present having had limited success in the past with Jenolite Rust Remover gel?
