Hi all,

I've picked up a nice old Philips portable, the 111D.
Its in good nick but ill be doing a slight cosmetic tidy-up and a re-cap.

What I'm interested in is building a battery eliminator for the unit, has anyone done this?
Ill post some pictures later today.

Cheers

Ahh I just found this - http://www.arbeiii.com/
10 times the cost of the radio..haha.

The quick and nasty way is 10 nine volt batteries in series for the B supply and a couple of D cells in parallel for the A supply. Make sure you get it around the right way.

I use a kit from Tony Maher of the HRSA in my portables, basically an inverter from 4 or 6 AA cells and outputs 90 volts. Tony has been rather ill of late and it might be hard to source a kit for the moment

I built one myself using a MC34063 switchmode IC. It worked but made a bit of RFI even when mounted in a aluminium box. I didn't have the interest to develop it further.

The arbeiii is a good power supply, but its only available in 110 volts. There is another chap who makes battery eliminator kits, I have one, but I cant recall his name.

Battery eliminators is a topic that gets discussed here fairly often, for instance:

Also tried that chip, unimpressed, you are right seems to use the ringing toroid as an antenna.

Tony Maher units are ok.

Depending on usage I frequently use cheap 9V batteries & a couple of "D" cells in parallel, you can use single holders, or modify a twin.

The 9V transistor batteries interlock (one up one down) & tape them together. Get an old one & split the top in half to make the terminals.
