Default Terminal Strips: Thumbs Up Or Down?

My original SSE build was without them figuring eliminating a connector was a good thing. I also didn't quite trust the little screw-downs.

Now that I have removed the wires from the board for the move to the new chassis and ruined more than one eyelet, I'm re-thinking. I like to tinker.

It's also a PITA to get tinned 18ga. into the smallish eyelets.

One option (that I did) was to install turrets into the board. That way I can solder/desolder to the turret instead of the board.

All older and reliable amplifiers were built with paxolin strip terminal strips. Dead easy to replace components and no through hole pcboard to worry about. Yes most definitely a yes!

The terminals make it all a bit too fiddly for me: while the principle is very good (you can easily reconfigure the amp), the time taken just to get two wires to stay put in the terminal holes while I screw them in tight is just too much. And it doesn't really work well, until the terminal casing itself gives way...

The holes should be wider.

The turrets seems a good idea.

These Euro style terminal blocks are idiot proof:

I use the bakelite terminal strips with soldering lugs in almost all my builds and rebuilds.... they come in many configurations...with or w/o ground lugs. Just bend the wire or wires, solder...

The original TSE board does not use the terminal strips. Many a board has been ruined by a user soldering or unsoldering a transformer wire. Response to the terminal strips has been favorable and I use them in all my projects to make things easier to build and take apart.

There have been no issues, with one exception. I would not use them in the final build of a guitar amp that will spend most of its life sitting on top of the speaker cabinet, especially if it is a bass guitar amp. The constant vibration will cause the screws to loosen over the years.
Tubelab, it's 5 year mission. To explore strange new tubes, to seek out new circuits and topologies, to boldly go where no tube has gone before......
