I have come across this little beauty I think its pretty rare I am not sure if it is I think its a 1933 model. Does anyone have a schematic for it and maybe what the original speaker fabric looked like.

It is a Timber radio and it has the letter H in timber (for healing I suppose) in front of the speaker fabric.
I need to do it all up.

Sanding work, so far:-



Thank you, George.

does anyone have a schematic for it

Can't find anything in the usual places. Even the Radiomuseum site is light on details for that particular set.

I don't know how to upload a photo of it.

As per the notes headed Quick Reply above the message posting box:

"6. If you want photos published with your post then please e-mail these to the administrator along with the name of the forum and the exact title of the thread you want them posted in."

(There's a clickable email address link in that note.)

Once we get a photo of it, it can be sent to Stuart Irwin for loading onto Radiomuseum.

I've got a circuit diagram for a Healing 403 & 43, dating from around 1934. The valve line up is 57, 58, 57, 2A5 & 80. The diagram doesn't show the power supply & rectifier, but that shouldn't be a problem.

Click on to my profile for my email details.

GTC, I'm not a member of Radiomuseum, but you can have a copy to forward to Stuart Irwin if you like.

Cheers.

I'm not a member either, but I'm in contact with Stuart from time to time so, yes, a copy of the schematic would be very handy.

BTW: Where did you find it?

I'm a member, but I have to find my login and password, been a while. my email wa2ise at ix dot netcom dot com (This email address I've had since 1995, so I'm already on every spammer list there is by now). So I could upload it,

I have forwarded the schematic to Stuart, who has created a very large number of entries for Australian radios on Radiomuseum.

Thank you for the diagram Monochrome625
Cheers George

Georges radio is a little beauty and would be a prize in anyone's collection.

I've just had a squizz at the HRSA models list. A point of interest is that the list says the model 403 is a console & the 43 is a mantle. Both use the same chassis/circuit (type 43).

It is not at all unusual for the same chassis to appear in several models, different cabinets and have different brand badges on the front (badge engineering).

The console chassis may only vary by having a speaker plug. This to enable the destruction of the OP valve when the set is powered up with the speaker unplugged.

This to enable the destruction of the OP valve when the set is powered up with the speaker unplugged.

Yes, indeed.

Wiser designers used a plug and socket that had an HT link in it, to remove voltage from the output stage when the speaker wasn't plugged in.

I did note a recommendation in SC re that. It referenced to a previous article in the vintage radio section, which I think related to comment on me actually modifiying a battery set, to eliminate that risk.

One should appraise sets & see if you can prevent that damage to Pentodes & Beam Tetrodes (Renodes) Where a screen grid can become the Plate when the real plate is open. Not all of the valves can withstand this abuse.

That radio will likely follow a fairly standard Autodyne "Screen Grid Radio" layout. As that is basically a standard vale lineup for one of them.

Marc

A rare radio, in particular with the speaker on the right and controls on the left. This layout was more common in New Zealand.

Best of luck with the restoration.

A valve a day keeps the transistor away...

I've been in contact with Stuart Irwin. He provided me with the scan of a page from "The Radio Retailer" 7 November 1933 issue which announces this as a new model. The mantel shown and described in detail is called 403 Minor. No mention of a console version at that time.

Unfortunately the quality of the scan doesn't allow us to see the speaker cloth detail, but I think we can assume it was plain.

Georgeandmargaret: Does yours have a chassis type number on it?

Stuart has now uploaded the photo and schematic to Radiomuseum:

I have finally finished it I will upload finished product so you can update the picture in the radio museum
