18 - Final Checks – DAC5.1
At this point we have completed the wiring of the DAC 5.1 – We have also successfully tested
the Power supply for 260-270V DC HT1 and HT2 – We also have 2 x 6.3V DC filaments .tested as
well.
It might be a good idea to make some of the following checks prior to first power up. Use an
ohm meter to make some checks – so we are checking for connectivity – if you have any
questions please contact us
18.1 Power UP & Testing
If you are ready for power up – then install the two line stage tubes – the 12au7 and the ECC99
into the correct positions (ECC99 closest to the output transformers.) Along with the 5U4G EH
tube in the power supply
If you power on and see all the tubes lit that’s a good start – you may want to double check the
HT1 and HT2 voltages which should be around 260v – you can definitely try the DAC in your
system if you are feeling confident – we are assuming a working power supply of course! Take
the SPDIF from your transport and connect to the SPDIF input on the rear of the DAC5.1 –
connect the analog outputs to an integrated amplifier or a pre-amplifier – consider this a line
output – Play some music through the transport into the DAC – if there is no sound you can
toggle the con1 con2 switch. If all goes well you are listening to some sweet music – if there is a
problem with either no sound or sound in one channel or a weak sound etc contact
audionotekits@rogers.com for support.
