Could anybody please help me aquire a copy of the Oz Radio Circuit CD/DVD mentioned on these pages?
I have an AWA R49 V which was built to run on batteries so I need to build a power supply for it. I can find no info on the valves either ?
They are 1L5G, 1K7G, 1D5G, and 1C7G
I would be most grateful for any assistance
Best regards from a damp London
Jon Fenwick

Jon,
I checked my disc and there is no AWA R49V listed. A couple of models have some of the valves that you listed but not all. Could send you the circuit of them if it helps or contact Ray Pedri vk6tibigpond.com he produced the disc.
Cheers
Rudy

With apologies to you Rudy,have been away and have only just seen your answer ! Many thanks.Will check with the CD producer for a copy. Theres no R49V eh ? The plot thickens. Would I be correct to assume the heater voltage is 2V and HT approx. 90V ?
Thanks again for your help,
Jon

Go to these sites for all the data you may need.

Hope it helps, if not I can look up my valve data book.

Cheers
