Need audio for my Vario's

[jb92563]

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.

one B-40 should do it.. and free up some panel space..

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.
