Hiya,

Noob user - so I hope I don't make too many blunders - apologies if I break any rules in my first post.

I have recently acquired both a Peter Pan Adventure Radio (CKP 6537) and an old Astor (PR 1422) from about the same vintage.

Hence the reason for my first post - What is the Best and Safest way to get the guts out of the case?

The Peter pan looks cooler (IMO) so it's the first one I'd like to attack.

I also need to re-glue some of the case (the skin is peeling away from one of the seams) - so additionally what's the best way to re-attach the skin?

I guess what I'm really saying is that I have so many questions I don't know which ones to ask FIRST..

Is there an "idiots guide to restoring your old valve radio" somewhere?, could someone point me at it please?

Thanks in advance

Welcome to the Forum.
For starters the Peter Pan "Adventurer" is possibly a model "CKP" dating from around late 1947.

Both Astor & Peter Pan radios will have a 2 or 3 letter model prefix stamped somewhere on the chassis.

EDIT: The Peter Pan "CKP" is, circuit wise, an improved version of the Astor "KP" from late 1946.

The Peter Pan CKP & Astor PR are both battery sets. They both use 2 X 45 volt "B" batteries for the HT & a 1.5 volt "A" for the valve filaments. "A" & "B" batteries have not been available for many years. The radios can be made to work by stringing together 10 X 9 volt batteries in series for the HT & some D cells in parallel for the filaments. Someone a while ago was making a step-up device that could deliver the HT voltage from just a couple of AA batteries.There also was a unit made by Astor to run the Peter Pan CKP on mains power.

G'day OldNerd,

Welcome to the forums.

Noob user - so I hope I don't make too many blunders - apologies if I break any rules in my first post.

Your first post was perfect. We are pretty informal here - as long as there's some mutual respect between members it's all good.

I've added some links to Monochrome's recent post regarding the two radios being discussed.

A valve a day keeps the transistor away...

Thanks for those Schematics (and words of encouragment).

Just wondering what sort of current do these sorts of radios draw?

90Vdc (whilst bitey, isnt that scary compared to some of the voltages I work with - suitable precautions need to be applied) but if I'm curious what sort of amps I would need to deliver..

Think milliamps rather than amps for these battery sets.
The current draw for both of these is 300 mA for the filament "A" supply and 12 mA for the HT "B" supply.

Thanks Harold.

Shouldn't be too hard to rustle up something suitable then...

90v . 12mA = Not very big at all.....
