Default Re: Redifon R153.

Hi Peter.

Thank you for the response of Redifon R150 s/n270. Thats true, the R150 is the cut down version of R50M. There is no selector to band below 550 khz, instead at the band selector, there is the duplicate band ABCDE but in Crystal Osc Mode not VFO. Inside the VFO Cage there is the Crystal socket.

Correct, only 465 KHz IF line. No 110 KHz IF.

PSU build in, Audio output transformer already in. There is a Jack at rear panel for speaker. On the right side of rear panel, there is a jack with many plug in, i think that is for muting or something.

There is Jack designated to IF Out at front panel. I follow the route, the connection is connected to the last IF Transformer.

Now busy with so many damage. Primary of IF 1, IF 2 need to be re-wounded. S meter was burned out. Some wiring was open by rat bites. Audio Potentiometer was open circuited.

Will updated on coming progress.
