Thought I might try my hand at repairing a small transistor radio. So I bought a Philips 90RL125 on that auction site just now. So far I have been unable to locate a schematic for it. If anyone has one or knows where I can find one I would love to hear from you.

A lot of those things had circuits within, otherwise they can be a rare beast. Some of the newer ones were IC and that poses an issue if it proves faulty.

The cold hard facts are, that if its too modern and the fault is not simple its e-waste. Many are similar to an autodyne.

Fixing procedures follow a similar plot as the methodology used in tube radio. An early printed circuit is prone to cracking; and that incudes joints. as are some horrid little axial caps around 3/8" by 1/2"crack & short. I have a Tandy MMS_10, that generates heat in the output and quite often cracks joints. It gets a lot of work.

Electrolytics often used for coupling do dry out and lose capacity causing low volume.

Circuit board soldered joints for external power supply and earphones are prone to cracking. Was a regular fix on a Sangean ATS 800.

Thanks Marcc and STC. Hopefully when it arrives it will have a schematic inside back cover. It is early 70's so I am hoping it's not too modern. Funnily though I had a possible cantidate kicking around my shed that I had recovered from a kerbside trash pile a few years ago. When I started thinking about transistors I started on it. As soon as I pulled the back off I noticed about three rather large IC's. It was working on FM but not AM. Those integrated circuits totally threw me so I buttoned it back up and put it aside. Now patiently waiting for the new victim to arrive.

I should have said external power supply and earphones jacks.
