Polytone Bass Amplifier, OP Amp discontinued!

Cole Mayert

I am trying to repair this old Polytone Bass Amp that my buddy bought in New York in the 80's. The problem is that the OP Amp inside that I do believe needs replacing is a discontinued item. The part number is an RC4739DB . I cannot find it anywhere for purchase, so I am wondering if anyone knows of a substitute or where to get a new one.

Let me know , Thanks!

Hi Cole,

I think you may need a pin to pin compatible amp to replace RC4739DB as you want to replace it in an already built system.
Let me see if there is something that match with the amp you're referring.

Cole,

Unfortunately I'm not able to find an exact pin to pin amplifier that fits in here. If you are open to other suggestions that are not pin to pin compatible we can look for other op amps.

Thank you, that is OK. I found a replacement on eBay actually. I should be alright.

Thanks,
