Philips & Mullard

A short history.

The first Australian Mullard sets were made by Airzone and then rebadged with the Mullard name. This was a common practice in the valve era.

Once Philips bought into Mullard, they produced rebadged versions of Philips sets.

There is much opinion in the world of collecting radios. Many collectors love Philips radios, while others think they are rubbish.

It is certainly a popular opinion that Philips sets are notoriously difficult to work on due to their "over-constructed' nature.

I think this is a carry over from their European origins. Most European sets give you the impression that someone held a competition to make the most complexly assembled cabinets.

The Mullard featured here is no different to it's Philips cousins.

To get the chassis out of the cabinet requires the removal of no less than 8 screws, some from deep inside the cabinet. Fine enough when you are removing them but drop one as you are reassembling the radio and you could be left pulling the whole thing apart again to find the dropped screw. (Yes, it did happen to me. TWICE!)

However one of the nice things about this design is that the components can be worked on without complete removal of the chassis thanks to a cardboard back that also goes under the cabinet. Take off just 2 screws on the bottom and you can replace any or all components under the chassis.

ill titleMullard MAS 1001D

A Simple Restoration.

ill_1The MAS 1001D is a rather up-market looking radio with it's white pinstripes on a mottled brown cabinet from around 1952-53.

It had been worked on prior to my acquiring it as I could see a number of resoldered joints underneath and one or two newer than original components were visible.

ill titleAs I found it...

Finding a schematic proved difficult however. My schematics listed Mullards up to a 1001A and a 1002 but no 1001D. So I looked for one that closely matched what I had but even this was difficult.

The valve lineup listed on the back of the set showed a 6AN7, 6N8, 6M5 and EZ82 rectifier. But inside the radio instead of the EZ82 I found a 6V4.

Was this even a 1001D? or did I have a mish-mash of chassis, cabinet and/or back?

In the end I discovered that the 6V4 is an American designation for the European EZ82 so along the way the 1001D had been repaired with a more readily available version of the rectifier.

Again the power cord was fairly ragged and needed to be replaced along with one paper capacitor that had dried out and cracked apart. The others looked to be OK.

Outside of these two simple replacements the radio needed no other electronic restoration.

Cosmetically the worst part was the grille cloth. It was intact but had many many rust spots on it. The worst from the steel screws fixing the speaker to the chassis.

I had recently gotten hold of some upholstery and curtain fabric swatches, several of which proved to be very capable replacements for 50's era grille cloth. I even let the wife help me choose the colour. She loved that!

Working perfectly and set up on the bedside table.

As a side note, if you are a collector who worries about dust accumulating in and on your radios, the WORST place to keep them would be the bedroom.

It only takes a week before the dust has built up all over any radio put there and they require constant dusting to keep them clean.
