Is that a PP sweep tube design in your breadboard pic? Tell us more.

Kevin K: Could I have your "West End" or West Side website address, please?

Terrific going on the SimpleSE. Even I can build one of those.

dmason,

No, nothing quite so interesting. Those are FAA-surplus NOS 6SN7GTBs which lack the usual octal base.

George et al,

When you use those screw-down terminals, are you able to securely grip several wires of differing gauges simultaneously? I have not tried your idea, preferring tack-soldering for a secure connection, because I was concerned that while one wire might be securely clamped, another might pull out. But maybe I should reconsider if it works well for you.

Hi Dmason,
I'm not West End or wevtt , the outfit you are referring to is a licensee of some of my designs and has a storefront on eBay. (No separate website)

My site is: www.kta-hifi.net

I do have all of my old books available through the wonders of lulu.com, but other than some consulting work I do from time to time and the articles I write for PFO I have pretty much ceased all commercial activity.

Multiple wires of similar size have not been a problem (solid or stranded). Multiple stranded wires of different sizes have not been a problem either. A fat stranded wire with several component leads works OK too. A fat solid wire with a thin solid wire can cause the thin one to come loose on some strips.

Look carefully into the end of the strip with the screw tight. Is there room for a wire to get in between the screw and the side of the hole. This is a problem with some surplus strips that I got. This is also why I use the smallest ones that I can find.
