Any info for McKay Dymek DR33?
Unfortunately it's not fully working, the synthesiser is working thankfully. but there's no audio other than expected power amp noise. The power supply regulators seem to have plausible voltages on them.
One clue is the signal meter swings to full deflection so perhaps an AGC fault silencing the output. It's a fairly complicated receiver so I really need a circuit diagram or even info on the IF board. Thanks, Lloyd. |

I did the previous posting in a hurry when I was travelling. I should have provided a link to this page:
http://www.prc68.com/P/Prod.html#DR33 which has the purchasing details for the US-origin CD that includes the DR33 service information. Please send me a PM if you need more background. Cheers, |

Thanks Synchrodyne, that looks like the only possible source.
