Need to find some cds photoresistors

Hello

Anybody have those cds photoresistors ?

NSL-7540, NSL7550, NSL-5160, NSL-5170

It's for my old HP-333A distortions analyser.

Thank

Bye

Hi,

perhaps you can find a suitable replacement if you have the datasheet - look at Digi-Key Corporation - USA Home Page and search for photoresistors. They have a selection of CdS photoresistors from Advanced Photonics (PDV-P????-ND) for example:

Digi-Key - PDV-P5001-ND (Advanced Photonix Inc - PDV-P5001)

so you can have a look and perhaps you can find a type suitable for you.

Hello

I will take a look.

Here is the specs of those cds photoresistors.

Thank

Hello

Maby I can filter out the output of my Xantrex to get less noise.

And for my sound system I can use an analog sinewave inverter using a ferroresonant transformator like this one that I include the schematic.

I have some MTP60N06HD power mosfet, I can use two of them in parallel for each side of the output.

I did ad, on the schematic, a diode between the LM324 out and the mosfet gate, and I would also ad a 100R resistor on those gate for less oscillations, but maby there is others mod to do.

Thank

Hello

I forfet to say that I allready have big transformer for that analog sinewave inverter using a ferroresonant transformator.
