Has anyone done this before? I'd be interested in trying modern opamp amps against discrete.
A small 2520 style pcb, but hold a DIP opamp?

Ioaudio had one of these that came with the meq500 project that are pretty slick.

Go to JLM Audio in Australia and look at his hybrid opamp in his Kits section. That's a 2520-sized board (with same pinout) that plops down a dual Burr-Brown OPA2604 and feeds the output into a discrete pair of transistors. You could cut-and-paste that board and get exactly what you want. Joe will sell you just the PCB because I have a few already. DW.

+1 for stripboard.
that's what I did, and I drop a 5524 in place of 2520 when i first fire it up. Just use veroboard, and cheap pind from Craplins.
If I can do it . . . .

Rob at Handcrafted tone had a design like this for etching. But his website seems to have disappeared.

Ha ha ha! That is surely what they have become. I wish I'd kept some of the early catalogues for a trip down memory lane.

Thanks - good ideas guys! The hybrid would work great.
By the way, I made a go between from stripboard, and in the end I felt like it was not worth the time to finish with something not quite as good.
I've become a big fan of pcbs. But to each his own.
I don't know what craplins is??? Is that the Radio Shack of Europe?
