I've got an old Mullard and am getting into restoration with vintage radios, I've just got a few questions: (I don't know if it's the right thread or not.)
1. Anything specifically to keep my eyes open for with this model (hot chassis?)
2. How common is the MAS1001 (Would it be easy to find another one if I find any issues?)
2. The Cabnet has had a rough coat of white in it's past, how easy is this to remove without damaging what's under?

Thanks,

MAS 1001 is a four valve transformer set. Not hot chassis.

Photo may be useful and photograph the works before you touch it.

It is a basis of need to know, with the paint. Like what is it on and what is it? Acrylic, or Enamel If you use Methylated spirits on the paint and it damages it. Then its most likely Acrylic.

Acrylic paint is often self stripping, when on Bakelite.

(This is the correct section and thanks for using a meaningful and useful thread title as opposed to ones like "Question".)

Info on this model here: https://www.radiomuseum.org/r/mullardaus_mas1001.html

Note the original colours available: Walnut, Burgundy & Brown. Ivory, Green & Blue

How common is the MAS1001 (Would it be easy to find another one if I find any issues?)

Hard to say definitively. I've seen them come up in HRSA auctions from time to time.

Rule No 1 for restos: Never power-up a radio that has not been in recent use. Doing so, without first checking for the usual suspects, can result in otherwise entirely avoidable damage to parts which can be expensive or unobtainable.

Rule No. 2. Google "Dim Bulb Tester".

What is your previous experience?

Do you have a meter? Know how to use it?

Enjoy!

The objective is to make an assessment of it first, before doing anything radical, or assuming the worst. And yes! I get asked to try and fix the damage after the exuberant, power it as a first step, to see if it works and let the smoke out.
