Rolling opamps: DIY DIP-14 to two DIP-8 socket converter for quad opamp to dual opamp

[ygg-it]

It is so hard to find in the market, that I decided to build myself.

Very useful for your listening tests and MODS.

This is a DIP-14 to two DIP-8 socket adapter to convert any quad opamp to two different dual opamps.

It contains also a 100nF rail-to-rail ceramic capacitor.

I'm permanently using in the pre-amplifier section of a Musical Fidelity A120 amplifier, where I temporary replaced JFET quad op-amp TL084 with two different superb bipolar chips (chosen after rolling several dual opamps, but still under listening test): Analog Device AD827 as unity gain buffer and Linear Technology LT1361 for volume gain.

To use this you need to unsolder your quad op-amp, that could be a tricky procedure.
Enjoy!

Another DIP8 combination

This is another outstanding bipolar configuration: Linear Technology LT1355 as unity gain buffer and Analog Device AD826 for volume gain.

Sound is slight less accurate and clean, but more emotional and warm-toned (thanks also to the well-known heavenly midrange of the AD826).

I stop here since the DIP8 combinations are nearly infinite..

Nice.

Would even allow one of the pair to be a discrete opamp, or a discrete Buffer.
And allow for a soic to dip8 converter
