Brown Dog RC4136 adapter

Don Nebel · 12th September 2006, 03:10 AM

Hello, I just received a couple of Browndog RC4136 to dual SO8 adapters. I am playing with an old AudioControl equalizer that uses RC4136 opamps. I would like to upgrade these opamps with newer devices. I have considered using 5532 SO8 devices. These devices have a higher slew rate than the RC4136 and are of a known quality when it comes to sound. I know that there are faster devices than the 5532 but, I am concerned about the ease of implementation in place of the RC4136. Please share your ideas about possible opamps to use in place of the RC4136 using the Browndog adapter.

OP275

How much are they going to charge for these things?

I think the price is going to be around $5.00 each.

About 10 years ago, I replaced the 4136 op amps in my Carver C-1 preamp. I used two DIP sockets with wire wrap wire to make the pinout conversion. The wire wrap was stiff enough to hold the socket and IC in the air. This worked well.

I used Burr-Brown OPA4134 quad op amps but they are no longer available in a DIP. You could buy the SO version and an adapter for it. Otherwise, you'll have to use the 275 or make up something using dual op amps.

Regards,

Greg
