Scophony Baird circuit diagram needed
Hello All, can anyone help me? I have a Scophony Baird,
http://www.vintagerecorders.co.uk/VR...age.asp?IDS=49 I have had it for a number of years and recently decided I would get it working, no sound output and lots of mains hum, I replaced almost all the non-electrolytic but the fault was still there, there is a mains ripple seen on the rectifier valve but I checked the smoothing caps and I tested the valve, removing it the amp side isn't working of course but the mains hum is still there, I now wonder if I connected a cap back in the wrong place. Does anyone have a diagram for this? its the older version with the larger octal valves. Many thanks. |
