Re: Getting a charity shop radiogram working
This unit is similar to the Dynatron SRX20 and you will find on this site a schematic of the unit and notes on the repair of specific faults.
In "search this site" enter the model.
Should you be unfamiliar with circuit diagrams, the turntable is connected to windings on the transformer and so the thermal fuse will be OK.
There are 2 other fuses. They can be easily seen. FS601 which protects the +18volt HT supply and FS603 in series with the 6.3 volt dial lamps and protects the transformer should they fail and become a short circuit. The bulbs should be working.
Should FS601 be blown showing a black smudge in the glass envelope then there is a fault.
Should it be blown but no blackening, you might be lucky and all it needs is to be replaced.
When you have your test meter, you will be able to check the fuses.
Do note that repairing any radio or amplifier equipment requires a degree of skill learnt from years of experience and members local to you may help, so there is no shame in asking.
