I just picked up a nice 1946 Breville model 330 radio chassis with excellent dial glass. It is missing the timber case anyone out there have a case they want to part with.

Hi Airzone,

I have a Breville which I am sure is a 330, but I could never distinguish between the model numbers. The cabinet styles varied in the detail.
How do you know which one you need and which one are you looking for?

See you an email Ian.

Hi Peter,

This web site indicates that your radio is a 330E ...... http://www.radiomuseum.org/r/breville_empire_mantel_330e_ch_330.html

Mine has a 6AN7 in front end .... and cabinet is same shape but different in detail. Photo in email to you and to Brad to add here.

Anyone know my Breville model number?

Thanks to Airzone for identifying my Breville ... not a 330 after all, but a 730. Model T.

I, prior to the current photo popping up, have sent Brad a front & Back photo of mine, which appeared in Silicon Chip. Its case is original.

It does not have 6AN7 its an Octal ECH33 or ECH35 that I repaired the shield on, 6U7; 6G8; 6V6; 5Y3.

If that one is similar it has 290V on load exiting the 5Y3, so I would use 600V filter caps. Be careful when aligning, its 446kHz and the first IF is band spread.

Not an overly difficult set. The usual suspects R17 & 18 are rarely in tolerance. Check the resistors as you change wax paper & all Electrolytic caps.

The rubber wire in this one was cactus especially the stuff going to the dial lights & I ended up repainting inside of that assembly.

The Number on this one is stamped into the chassis on the right side of the PU plug on the lower edge.

Hi Mark.

Re 6AN7 - I will probably go back to a ECH33 or 35 ... may have one in a 'parts' set.

Re chassis number ..... cannot believe that I missed that number (a good torch helped) .... yes, there is a number stamped into the chassis, lower right side when viewing from rear ...... 7303354 There is that 730 number again .....

Have noted your other advice, thanks.

.... BTW ..... GO DOGGIES

Apologies to Airzone for unintentionally highjacking his Thread ......

...... Airzone needs a case for his Breville 330 .....

The point, with the 330 is that it may be stamped in a similar fashion and it is not unreasonable for the rubber wire to be equally as bad.

What I said about caps & resistors, still applies. The circuit of 330 is similar & the 600V filter caps still apply.

At least we are now 100% sure of what yours is. ECH35 replaces ECH 33: 6J8 will work in the same hole, but it is not shielded. 330 is shown with an EK2G or 6J8 so that may be a guide to any resistance changes needed in the 730.

Photos uploaded to Post 8.

I too have one of these but it requires a complete overhaul and cabinet restoration. I don't remember whether mine has two of the chrome speaker 'grillettes' or four. I've seen examples of where some have two and some have four and that is the case with the posted photos too.

Brad. Thanks for posting.

These photo's show that there has been every effort by Breville to "show off" what model this is. Despite it being painted black with conductive glue and having a spiral wire added etc. That is an ECH 35 with a new fly lead.

Not real obvious in the photo but with cloth covered wire a thin band of shrink tube stops it fraying (as does circuit board lacquer). Shrink tube can also reinforce the TC terminal to lead join on many & stop it shorting onto some shields.

This one may have been a "High end model", I was made aware that my Aunt, bought it second hand.

Hi all,

Some 'surfing' around the web located this list of Breville models ...... http://www.hws.org.au/RadioHistory/manufacturers/Breville.htm

See 1948 ... there are two models listed 730C and 730T.

The AORSM and HRSA references to circuit diagrams are to the same pages ....... suggesting that the circuits are the same.

I am assuming that C => Console T => Mantle ...... Consoles are usually big, bulky cabinets ?? whereas the radios in photos above are Mantles.

But maybe there is variation to the styles ie. 2 'grillettes' versus 4 ????? .....


Any thoughts??

I have a Breville that looks something like these, with the sloping dial glass, but it uses miniature valves.

The glass had fallen into the radio and it was a real mess. I cleaned out the huge amount of dust, reattached the glass inside the case, and got it to work again. But the cabinet needs an overhaul. I don't know the model number.
