Many thanks to datasheet archive for having scanned the uA706 !! I read there that a version of the uA706 in a metal case does not exist! So, how could be the mapping between the 10706NB and the uA706 .. I don't know. I think I will experiment it basing on the layout of the 10 pin metal case MC1530 and I will inform the list about the results. Bye
Why are you looking at yet another obsolete op-amp ( MC1530 ) ?
The performance of the uA 706 is dismal btw . Don't waste any time on it.

Graham, I implemented many effects from Electronic Projects for Musician (a book written by Craig Anderton in 1977). I built a Phase Shifter with an Envelope Follower inside, the Ultra Fuzz, the Ring Modulator, the Tube Sound Fuzz(using CMOS), the Super Tone Control (with the possibility to connect to the Envelope follower). I found a replacement for EVERY obsolete parts (like RC4739), without modifing **anything** in the circuitry. When I tried to implement the MiniAmp, I discovered that he used too old components. So before giving up definitely and redirect my attention to an OPA2134 or TDA2030 MiniAmp based project, I wanted to do some "electronic archeology" on this 10706NB by rockwell who is
**supposed** to be a clone of the uA706. Moreover, I like to believe that my work could be useful for those who, like me, will face the same old VINTAGE project and would bring new life to it. I didn't buy any MC1530, but this component is the only 10 pin metal case component datasheet I found and I hope to make a pin-2-pin match with the already bought 10706NBThank-you for your attention and your advises
Bye
Note that the OPA2134 is an op-amp ( operational amplifier ) for use in this case as a pre-amp stage only.
Quite unlikely I suspect, although you could be right in this case Audio power amp chips ( unlike op-amps ) do not tend to have a common design, pinout or characteristics. In fact almost every one seems to be pretty much unique.
I think you're mistaken there. The 'project' you're looking at it would benefit from being thrown in the bin and re-designed from scratch. Copying it is the very worst thing you could do. It has several areas where the design is frankly very poor.
Very unlikely indeed. The choice of a ten pin package has no connection with likely pinout.
You're welcome. Now I recommend you consider building that TDA2030 pcb.
