R1155
Hello all
I have just aquired a R1155 receiver in perfect original condition. I do not want to make any alterations to this so I need a circuit diagram or plans to build a seperate power supply with a built in audio amplifier. Has anyone undertaken this or could advise where to look. Many thanks Mike. |

Hi Mike
Have you seen the original Wireless World article from July 1946 on Maurice Woodhead's site? It includes a power supply design and output stage. The link is http://vintageradio.me.uk/military/1155_ww1946.htm Ron |

Re: R1155
The key thing to note about powering the R1155 is the unusual relationship between ground and HT- which tends to preclude regular power supply designs.
