I am going to experiment with several GC schematic configs with several different IC's (LM1875, LM3785, LM3886, OPA541), and this experimentation phase would go much smoother if I could use a power ZIP socket for the power amp IC's. I have searched the archives here, searched the usual parts suppliers and done a general internet search but have not been able to find a suitable socket. Because of the pin spacing, I have also not been able to find a SIP socket that could cobbled together with 2 offset rows. Anyone here have any success in getting sockets for these IC's?

these chips like very short lead lengths -- to do otherwise is to invite problems --
one thing you could try is to get some sockets with machined pins and take them apart -- you can also buy hole type contacts from places like Allied Electronics and Newark Electronics.
the other thing you can do is bend the pins at 90 degrees (gently, they do break) and tack solder them to the board.

Yes, I understand that lead length is a concern but I only plan to use sockets during the experiment/comparison phase. Once I narrow down the choices I will use point-to-point wiring directly to the IC leads for the final product.
My idea for the comparison phase is to use point-to-point wiring to the socket leads, allowing me to build up several versions on several sockets. Then I can quickly try several configs without needing (or continually modifying and perhaps destroying) a bunch of amp IC's; the TI parts are not cheap. This would also reduce the rework/resoldering directly on the IC's. Given the lack of readily available sockets (and the fact that none of the amps have compatible pin-outs), I'll just proceed with point-to-point wiring on the IC's.
Thanks!
