Dear All,
I am not a tech so I have little knowledge of what I am asking for. I recently bought a few radios as I love old valve technology. I have a friend who was prior to retirement a tech at Telstra and has said he will help me restore this set as it hums and has all old caps etc. but has asked me to find a circuit for it, so I have joined this site hoping somebody may be able to help me with this.
I have no Idea how to post some photographs here and being a professional photographer could supply good clear photographs if I could work out how to up load.
Anyway the set is a wooden cased unit and measures L 59cm x H 32cm x D 29cm.
The front is Speaker grill to the left and horizontal dial to the right with magic eye tube in top right side of dial.
It is a 5 band radio with a triple gang v/condenser.
The tubes are largest being I think the rectifier and marked Raytheon 80, 7A7 X 2, 7A8, and two I can't read.
The chassis has a no on it but probably only a manufacturers no of RO 96853. It also has an extension speaker outlet in the rear of the chassis.
If anyone can help me with a circuit diagram or if you require a photograph of the chassis and unit and can tell me how to upload or give me an address to send to I will do so.
Thanks to anyone who can help me.

Regards

Paul Cohen.

G'day Paul,

Welcome to the forums. Please e-mail me any photos you'd like embedded in your post and I will upload them for you. An alternative is to use a hosting service like Photobucket but the first idea is much easier and guarantees your photos will always be accessible.

I don't have any info for that line up.

It's most likely manufactured in NZ. Radiomuseum says:

Radio Ltd. in Auckland (and later Radio (1936) Ltd.) were New Zealand's largest manufacturers. As well as their main brand "Ultimate" they made "Courier", "Crusader", "Hamilton", "Golden Knight", "Lewis Eady", "Luxor", "Madison", "National", "Paramount", "Rolls" and "Skyscraper" branded radios. "Ultimate" branded radios were exported to Australia from 1935 to 1940.

I would try these guys for a schematic:

GTC hit the nail on the head. The dial glass is the evidence here, with several NZ stations showing for the broadcast band. This radio also has a magic eye tuning indicator and four shortwave bands. It was probably an up-market receiver in its time.
