I have a Cambridge and early Ball varios but neither one has the
external audio units. Are there schematics for these circuits so I can build a couple. I do have a fried Cambridge AU20 audio unit that has a blown capacitor on it but it seems that these circuits are very simple and should be fairly easy to make some for my vario's since I do not think they are sold anymore. I also have a vario audio unit that has the static & pitot lines going into it as a separate unit for audio only, and I do not think it is working either. Does anyone have any suggestions? or do I have to buy 3 Borgfelt B50 varios to get audio again. Ray Buhr |

I've got an old Ball Vario, with an external audio box.
I don't think that the Vario is usable any longer. I'll be happy to send you the audio box for the cost of shipping. Contact me at the email below if you would like it. dave r. davidr5 @ yahoo.com "jb92563" wrote in message oups.com...
