PM5109 service manual needed.

(1/3) > >>

Turbon:
Hi.

There are manuals for the more advanced Philips generators on the net but I can't find one for this. Could someone point me to a free one please. It belongs with the others at elekrotanya or an similar place.

Regards

Add Fluke before the model number and you should get a few hits to choose from.

I did not find the service manual but it is a relatively simple test gear that should be able to repair even without this documentation.

I have a PM5109 in good condition and I could make some measurements to help you repair your own.

This is probably a RC bridge of Wien oscillator with double potentiometer to vary the frequency.

On the printed board, there are 3 separate blocks: the symmetrical power supply, the oscillator and the output amplifier.

HighVoltage:
Look or ask at the vintage radio forum in the UK
There are some people active that are in to older philips gear.

Turbon:
Thank you for your suggestions and answers. It ain't broken but I find the distorsion a bit high so I would need the schematic to see what to tweak to get it down. Most for fun as I do have some fixed frequency oscillators for more serious measurements if needed.

Regards
