I've had this radio for a few years now, and have done the usual cleanup and re-cap, but with limited success. I'm hampered by not having a circuit diagram, and I'm hoping that someone here may be able to help. The valve lineup is from L to R: 6A8G, 6U7G, 6B6G, 6F6G and 5Y3G. Photos are from before any work was done, when it was the way it should be to start with: untouched! If anyone knows any history of this brand, and a possible age in addition to a diagram, I'd be interested. Cheers, Alan

The only reference I can find to Claritone is A W Dobbie & Co - Adelaide 1934 - 1935. Your valve lineup matches quite a few Australian radios from Airzone, AWA, Aristocrat and others in the 1938-1941 period. Sorry, not much help really.

Scraps is correct. Claritone was the house brand for A. W. Dobbie of Adelaide. The Claritone brand was around from 1931 to possibly the 1960's. There were even a couple of Claritone TV models around. This radio going by the ARTS&P sticker indicates a 1940 vintage. The chassis looks like it well could of been made by Eclipse. Why I'm thinking Eclipse is because the power transformer is a Radio Corp/Electronics Industries type & the gold "Danger" decal is the same type used over the years by Astor. Earlier Claritone radios used Saxon paper caps which were made by Eclipse. Eclipse were well known for supplying generic radios for retailers to put their own brand on. The AORSM Volume 2 of 1938 models has a schematic for a Dual Wave Eclipse EJL. This has the same valve line-up (apart from a 80 rectifier) as the Claritone.

Thank you for that. My problem of not having previously had a diagram was exacerbated by being slightly colourblind, so faded colours are even less decipherable! Hopefully now I'll have sound. Cheers, Alan.

The Eclipse circuit uploaded to this thread is for a guide only. It was chosen because I think the Claritone may be using an Eclipse chassis. Also, comparing the photos of underneath the chassis to the schematic looks pretty close, right down to the large 10 meg resistor between the grid of the 6B6G to ground. The volume control set up in the schematic is something I haven't seen before. It is best to compare the chassis with the circuit before working on it. It may well be that the Claritone chassis is based on the Eclipse circuit but with some differences.

"The volume control set up in the schematic is something I haven't seen before." Can't see any sign of an AGC circuit so maybe this sort of volume control working on the aerial signal and the bias of the 6A8 and 6U7 helps to ensure that the volume can be turned down to no sound.
