Just picked this one up today from a relative of original owner.

From what I can find on Radio Museum site going by valve lineup, it appears to be 1938 model 587.

Valve lineup 6K7G 6U7G possibly 75, six pin but can't read type 6V6GT is fitted but could originally have had 6F6G and an 80.
6V6 could have been fitted when it went for repair in 1960 with low volume fault as per attached tag on chassis.

Has a Garrard 78RPM only turntable with replaceable needles.

Haven't removed chassis yet.

Have taken some photos and sent to Brad for upload.

AORSM CD is only from1940 for Peter Pan the cathode resistor, if fitted will be the clue as to what the OP tube should be. and with 6V6 the grid 1 resistors are normally 500K & stuffed. It often has a 50K grid stopper resistor it will also likely be a dud. That whole family of OP tubes tend to do that & the plate resistor on the first audio has a similar attrition rate.

75 is definitely pre 1940 but not before 1933 as that is when 75 was introduced. Electrically it became 6SQ7 in octal form.

I have a radio with the same station display etc.

This might help: https://vintage-radio.com.au/default.asp?f=2&th=666

There are a couple of things to note on this one:

Confirm which coil is fried: It is very unusual to find both aerial coils fried, albeit I have an STC here with two separate coils open.

Its "back biased" so the first filter cap does not ground.

That is a "shielded transformer", so will bleed charge to the chassis. Chasses with that sort of transformer will never leave here without it being mains grounded chassis. One here recently had 55V on the non grounded chassis (DVM). The transformer was shielded not faulty.

I would at a minimum check the primary for earth leakage per regulations and make sure nothing "mains" that side is going to a non grounded chassis. One needs to get to the bottom of "WHY" if the coils are actually melted. It would not ever be unusual for it to be turned to SW to see if it worked, (& vise versa) when the set failed.

Thank Brad for uploading the photos.
I know you have been quite busy with getting this forum back up and running.

Will post photo of under side chassis and dial assembly when I have removed chassis from cabinet.
A stated above I think it appears to be 1938 model 587.

Thanks for all your comments so far.

It is likely 1940, as indicated by the "G" on the ARTS&P label, although it looks like the 587 type chassis was used 1938 to 1939 and possibly into early 1940. The serial number on the ARTS&P transfer is very low so that indicates a manufacture date of early 1940. The converter would be a 6K8G not a 6K7G. A 6V6GT will substitute for a 6F6G but not the other way around. It is possible though that this particular radio was manufactured with a 6V6G, as Peter Pan (Eclipse, taken over by Radio Corp in 1939) started to switch to the 6V6G by this time. A clue would be the 250 ohm back bias resistor. If it is less than this, say 150 ohms, it may originally have used the 6V6G.

Hope that is of some help. Cheers, Stuart.

Thanks Stuart, it has a 6K8G, my error not a 6K7. When I took a photo of the chassis noticed there were valve types on the chassis.
Couldn't read first one, but is 6K8G,then 6U7G 75 6F6G 80. The 6V6GT may have been a mod when it was repaired in 1960.
It has a 7000 ohm speaker transformer.
Just removed the chassis today, will send Brad photos of chassis and under chassis.

Photos uploaded to Post 6. Apologies for the delay, due to being in Melbourne for their last big auction for the year.

Yep, a white and green Astor AR Baby. In fairly good nick too. Photo to come tomorrow night.

Sounds like you enjoyed your weekend in Melbourne.

It was a good weekend but would have been better without the mozzies. I have 240V in the car and should have had my Mortein mozzie zapper with me. I did the usual thing and stayed in the back of my car on Friday night (it's a proper wagon so plenty of room) and stayed at my usual motel on Saturday night.

Today I did whistle-stop tours of Shepparton, Benalla and Wangaratta to check out a few antique shops but didn't find anything inspirational.

Inspirational would have perhaps been Yackandandah, I have repaired a few from a collector in that direction. If you like clutter grams there are some in a container here. There are a couple of radio's (for a price) at the Dookie Emporium.

Electrics look like a wet afternoon job seeing it was only half fixed. If the transformers are OK? New earthed cable with grommet, pointy end in; Globes look tired; What looks like Cheney caps out; Filter caps look too big in capacity 500V, x μF; If the resistor is green & yellow or green and orange (eg grid of OP tube) its probably a dud.

Tatty is the resistor starting red red possibly 220K plate resistor might have been better to go to the dead pin 6 on the OP socket, the coupling cap to pin 6, then a wire close to the chassis from pin 6 to what I believe is the 75 Plate (pin2). Not surprised to see a new resistor there, check it, they have a high attrition rate. Looks like field coil in negative & back biased on the "candohm" resistor, which are also notorious for corrosion & failing.

Chassis: Not many hours of productive amusement ahead: As said wet afternoon.

I went to Yackandandah some years ago, I think it was about ten years ago. It's main industry at the time seemed to be antique shops and pie shops. I fitted right in.
